+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at fafhrd91@gmail.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

+## 0.7.4
+
+* `Route::with_config()`/`Route::with_async_config()` always passes configuration objects as tuple
+  even for handler with one parameter.
+
+
+## 0.7
+
+* `HttpRequest` does not implement `Stream` anymore. If you need to read request payload
+  use `HttpMessage::payload()` method.
+  
+  instead of
+  
+    ```rust
+    fn index(req: HttpRequest) -> impl Responder {

+            .fold(...)
+            ....
+    }
+    ```
+
+* [Middleware](https://actix.rs/actix-web/actix_web/middleware/trait.Middleware.html)
+  trait uses `&HttpRequest` instead of `&mut HttpRequest`.
+
+* Removed `Route::with2()` and `Route::with3()` use tuple of extractors instead.
+    
+    instead of 
+
+    ```rust
+    fn index(query: Query<..>, info: Json<MyStruct) -> impl Responder {}
+    ```
+
+    use tuple of extractors and use `.with()` for registration:
+
+    ```rust
+    fn index((query, json): (Query<..>, Json<MyStruct)) -> impl Responder {}
+    ```
+
+* `Handler::handle()` uses `&self` instead of `&mut self`
+
+* `Handler::handle()` accepts reference to `HttpRequest<_>` instead of value
+
+* Removed deprecated `HttpServer::threads()`, use 
+  [HttpServer::workers()](https://actix.rs/actix-web/actix_web/server/struct.HttpServer.html#method.workers) instead.
+
+* Renamed `client::ClientConnectorError::Connector` to
+  `client::ClientConnectorError::Resolver`
+
+* `Route::with()` does not return `ExtractorConfig`, to configure
+  extractor use `Route::with_config()`
+
+    instead of

+## 0.6
+
+* `Path<T>` extractor return `ErrorNotFound` on failure instead of `ErrorBadRequest`
+
+* `ws::Message::Close` now includes optional close reason.
+  `ws::CloseCode::Status` and `ws::CloseCode::Empty` have been removed.
+
+* `HttpServer::threads()` renamed to `HttpServer::workers()`.
+
+* `HttpServer::start_ssl()` and `HttpServer::start_tls()` deprecated.
+  Use `HttpServer::bind_ssl()` and `HttpServer::bind_tls()` instead.
+
+* `HttpRequest::extensions()` returns read only reference to the request's Extension
+  `HttpRequest::extensions_mut()` returns mutable reference.
+
+* Instead of 
+
+   `use actix_web::middleware::{
+        CookieSessionBackend, CookieSessionError, RequestSession,
+        Session, SessionBackend, SessionImpl, SessionStorage};`

+
+   `use actix_web::middleware::session{CookieSessionBackend, CookieSessionError,
+        RequestSession, Session, SessionBackend, SessionImpl, SessionStorage};`
+
+* `FromRequest::from_request()` accepts mutable reference to a request
+
+* `FromRequest::Result` has to implement `Into<Reply<Self>>`
+
+* [`Responder::respond_to()`](
+  https://actix.rs/actix-web/actix_web/trait.Responder.html#tymethod.respond_to)
+  is generic over `S`
+
+*  Use `Query` extractor instead of HttpRequest::query()`.

+   }
+   ```
+
+   or
+
+   ```rust
+   let q = Query::<HashMap<String, String>>::extract(req);
+   ```
+
+* Websocket operations are implemented as `WsWriter` trait.
+  you need to use `use actix_web::ws::WsWriter`
+
+
+## 0.5
+
+* `HttpResponseBuilder::body()`, `.finish()`, `.json()`
+   methods return `HttpResponse` instead of `Result<HttpResponse>`
+
+* `actix_web::Method`, `actix_web::StatusCode`, `actix_web::Version`
+   moved to `actix_web::http` module

+* `actix_web::header` moved to `actix_web::http::header`
+
+* `NormalizePath` moved to `actix_web::http` module
+
+* `HttpServer` moved to `actix_web::server`, added new `actix_web::server::new()` function,
+  shortcut for `actix_web::server::HttpServer::new()`
+
+* `DefaultHeaders` middleware does not use separate builder, all builder methods moved to type itself
+
+* `StaticFiles::new()`'s show_index parameter removed, use `show_files_listing()` method instead.
+
+* `CookieSessionBackendBuilder` removed, all methods moved to `CookieSessionBackend` type
+
+* `actix_web::httpcodes` module is deprecated, `HttpResponse::Ok()`, `HttpResponse::Found()` and other `HttpResponse::XXX()`
+   functions should be used instead
+
+* `ClientRequestBuilder::body()` returns `Result<_, actix_web::Error>`
+  instead of `Result<_, http::Error>`
+
+* `Application` renamed to a `App`
+
+* `actix_web::Reply`, `actix_web::Resource` moved to `actix_web::dev`

-# Websocket chat example
-
-This is extension of the
-[actix chat example](https://github.com/actix/actix/tree/master/examples/chat)
-
-Added features:
-
-* Browser WebSocket client
-* Chat server runs in separate thread
-* Tcp listener runs in separate thread
-
-## Server
-
-Chat server listens for incoming tcp connections. Server can access several types of message:
-
-* `\list` - list all available rooms
-* `\join name` - join room, if room does not exist, create new one
-* `\name name` - set session name
-* `some message` - just string, send message to all peers in same room
-* client has to send heartbeat `Ping` messages, if server does not receive a heartbeat message for 10 seconds connection gets dropped
-
-To start server use command: `cargo run --bin server`
-
-## Client
-
-Client connects to server. Reads input from stdin and sends to server.
-
-To run client use command: `cargo run --bin client`
-
-## WebSocket Browser Client
-
-Open url: [http://localhost:8080/](http://localhost:8080/)

-# Quick start
-
-Before you can start writing a actix web application, you’ll need a version of Rust installed.
-We recommend you use rustup to install or configure such a version.
-
-## Install Rust
-
-Before we begin, we need to install Rust using the [rustup](https://www.rustup.rs/) installer:
-
-```bash
-curl https://sh.rustup.rs -sSf | sh
-```
-
-If you already have rustup installed, run this command to ensure you have the latest version of Rust:
-
-```bash
-rustup update
-```
-
-Actix web framework requires rust version 1.20 and up.
-
-## Running Examples
-
-The fastest way to start experimenting with actix web is to clone the actix web repository
-and run the included examples in the examples/ directory. The following set of
-commands runs the `basics` example:
-
-```bash
-git clone https://github.com/actix/actix-web
-cd actix-web/examples/basics
-cargo run
-```
-
-Check [examples/](https://github.com/actix/actix-web/tree/master/examples) directory for more examples.

-# Middlewares
-
-Actix middlewares system allows to add additional behavior to request/response processing.
-Middleware can hook into incoming request process and modify request or halt request 
-processing and return response early. Also it can hook into response processing.
-
-Typically middlewares involves in following actions:
-
-* Pre-process the Request
-* Post-process a Response
-* Modify application state
-* Access external services (redis, logging, sessions)
-
-Middlewares are registered for each application and get executed in same order as
-registration order. In general, *middleware* is a type that implements
-[*Middleware trait*](../actix_web/middlewares/trait.Middleware.html). Each method
-in this trait has default implementation. Each method can return result immediately
-or *future* object.
-
-Here is example of simple middleware that adds request and response headers:
-
-```rust
-# extern crate http;
-# extern crate actix_web;
-use http::{header, HttpTryFrom};
-use actix_web::*;
-use actix_web::middleware::{Middleware, Started, Response};
-
-struct Headers;  // <- Our middleware
-
-/// Middleware implementation, middlewares are generic over application state,
-/// so you can access state with `HttpRequest::state()` method.
-impl<S> Middleware<S> for Headers {
-
-    /// Method is called when request is ready. It may return
-    /// future, which should resolve before next middleware get called.
-    fn start(&self, req: &mut HttpRequest<S>) -> Result<Started> {
-        req.headers_mut().insert(
-            header::CONTENT_TYPE, header::HeaderValue::from_static("text/plain"));
-        Ok(Started::Done)
-    }
-
-    /// Method is called when handler returns response,
-    /// but before sending http message to peer.
-    fn response(&self, req: &mut HttpRequest<S>, mut resp: HttpResponse) -> Result<Response> {
-        resp.headers_mut().insert(
-            header::HeaderName::try_from("X-VERSION").unwrap(),
-            header::HeaderValue::from_static("0.2"));
-        Ok(Response::Done(resp))
-    }
-}
-
-fn main() {
-    Application::new()
-       .middleware(Headers)  // <- Register middleware, this method could be called multiple times
-       .resource("/", |r| r.h(httpcodes::HTTPOk));
-}
-```
-
-Active provides several useful middlewares, like *logging*, *user sessions*, etc.
-
-
-## Logging
-
-Logging is implemented as middleware. 
-It is common to register logging middleware as first middleware for application. 
-Logging middleware has to be registered for each application.
-
-### Usage
-
-Create `Logger` middleware with the specified `format`.
-Default `Logger` could be created with `default` method, it uses the default format:
-
-```ignore
-  %a %t "%r" %s %b "%{Referer}i" "%{User-Agent}i" %T
-```
-```rust
-# extern crate actix_web;
-use actix_web::Application;
-use actix_web::middleware::Logger;
-
-fn main() {
-    Application::new()
-       .middleware(Logger::default())
-       .middleware(Logger::new("%a %{User-Agent}i"))
-       .finish();
-}
-```
-
-Here is example of default logging format:
-
-```
-INFO:actix_web::middleware::logger: 127.0.0.1:59934 [02/Dec/2017:00:21:43 -0800] "GET / HTTP/1.1" 302 0 "-" "curl/7.54.0" 0.000397
-INFO:actix_web::middleware::logger: 127.0.0.1:59947 [02/Dec/2017:00:22:40 -0800] "GET /index.html HTTP/1.1" 200 0 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:57.0) Gecko/20100101 Firefox/57.0" 0.000646
-```
-
-### Format
-
- `%%`  The percent sign
-
- `%a`  Remote IP-address (IP-address of proxy if using reverse proxy)
-
- `%t`  Time when the request was started to process
-
- `%P`  The process ID of the child that serviced the request
-
- `%r`  First line of request
-
- `%s`  Response status code
-
- `%b`  Size of response in bytes, including HTTP headers
-
- `%T`  Time taken to serve the request, in seconds with floating fraction in .06f format
-
- `%D`  Time taken to serve the request, in milliseconds
-
- `%{FOO}i`  request.headers['FOO']
-
- `%{FOO}o`  response.headers['FOO']
-
- `%{FOO}e`  os.environ['FOO']
-
-
-## Default headers
-
-To set default response headers `DefaultHeaders` middleware could be used.
-*DefaultHeaders* middleware does not set header if response headers already contains
-specified header.
-
-```rust
-# extern crate actix_web;
-use actix_web::*;
-
-fn main() {
-    let app = Application::new()
-        .middleware(
-            middleware::DefaultHeaders::build()
-                .header("X-Version", "0.2")
-                .finish())
-        .resource("/test", |r| {
-             r.method(Method::GET).f(|req| httpcodes::HTTPOk);
-             r.method(Method::HEAD).f(|req| httpcodes::HTTPMethodNotAllowed);
-        })
-       .finish();
-}
-```
-
-## User sessions
-
-Actix provides general solution for session management. 
-[*Session storage*](../actix_web/middleware/struct.SessionStorage.html) middleware can be 
-use with different backend types to store session data in different backends. 
-By default only cookie session backend is implemented. Other backend implementations 
-could be added later.
-
-[*Cookie session backend*](../actix_web/middleware/struct.CookieSessionBackend.html)
-uses signed cookies as session storage. *Cookie session backend* creates sessions which
-are limited to storing fewer than 4000 bytes of data (as the payload must fit into a
-single cookie). Internal server error get generated if session contains more than 4000 bytes.
-
-You need to pass a random value to the constructor of *CookieSessionBackend*.
-This is private key for cookie session. When this value is changed, all session data is lost.
-Note that whatever you write into your session is visible by the user (but not modifiable).
-
-In general case, you create
-[*Session storage*](../actix_web/middleware/struct.SessionStorage.html) middleware
-and initializes it with specific backend implementation, like *CookieSessionBackend*.
-To access session data
-[*HttpRequest::session()*](../actix_web/middleware/trait.RequestSession.html#tymethod.session)
-method has to be used. This method returns
-[*Session*](../actix_web/middleware/struct.Session.html) object, which allows to get or set
-session data.
-
-```rust
-# extern crate actix;
-# extern crate actix_web;
-use actix_web::*;
-use actix_web::middleware::{RequestSession, SessionStorage, CookieSessionBackend};
-
-fn index(mut req: HttpRequest) -> Result<&'static str> {
-    // access session data
-    if let Some(count) = req.session().get::<i32>("counter")? {
-        println!("SESSION value: {}", count);
-        req.session().set("counter", count+1)?;
-    } else {
-        req.session().set("counter", 1)?;
-    }
-
-    Ok("Welcome!")
-}
-
-fn main() {
-#   let sys = actix::System::new("basic-example");
-    HttpServer::new(
-        || Application::new()
-            .middleware(SessionStorage::new(          // <- create session middleware
-                CookieSessionBackend::build(&[0; 32]) // <- create cookie session backend
-                    .secure(false)
-                    .finish()
-            )))
-        .bind("127.0.0.1:59880").unwrap()
-        .start();
-#     actix::Arbiter::system().send(actix::msgs::SystemExit(0));

-# Database integration
-
-## Diesel
-
-At the moment of 1.0 release Diesel does not support asynchronous operations.
-But it possible to use `actix` synchronous actor system as a db interface api.
-Technically sync actors are worker style actors, multiple of them
-can be run in parallel and process messages from same queue (sync actors work in mpmc mode).
-
-Let's create simple db api that can insert new user row into sqlite table.
-We have to define sync actor and connection that this actor will use. Same approach
-could used for other databases.
-
-```rust,ignore
-use actix::prelude::*;*
-
-struct DbExecutor(SqliteConnection);
-
-impl Actor for DbExecutor {
-    type Context = SyncContext<Self>;
-}
-```
-
-This is definition of our actor. Now we need to define *create user* message and response.
-
-```rust,ignore
-#[derive(Message)]
-#[rtype(User, Error)]
-struct CreateUser {
-    name: String,
-}
-```
-
-We can send `CreateUser` message to `DbExecutor` actor, and as result we get
-`User` model. Now we need to define actual handler implementation for this message.
-
-```rust,ignore
-impl Handler<CreateUser> for DbExecutor {
-    type Result = Result<User, Error>
-
-    fn handle(&mut self, msg: CreateUser, _: &mut Self::Context) -> Self::Result
-    {
-        use self::schema::users::dsl::*;
-
-        // Create insertion model
-        let uuid = format!("{}", uuid::Uuid::new_v4());
-        let new_user = models::NewUser {
-            id: &uuid,
-            name: &msg.name,
-        };
-
-        // normal diesl operations
-        diesel::insert_into(users)
-            .values(&new_user)
-            .execute(&self.0)
-            .expect("Error inserting person");
-
-        let mut items = users
-            .filter(id.eq(&uuid))
-            .load::<models::User>(&self.0)
-            .expect("Error loading person");
-
-        Ok(items.pop().unwrap())
-    }
-}
-```
-
-That is it. Now we can use *DbExecutor* actor from any http handler or middleware.
-All we need is to start *DbExecutor* actors and store address in a state where http handler 
-can access it.
-
-```rust,ignore
-/// This is state where we will store *DbExecutor* address.
-struct State {
-    db: SyncAddress<DbExecutor>,
-}
-
-fn main() {
-    let sys = actix::System::new("diesel-example");
-
-    // Start 3 parallel db executors
-    let addr = SyncArbiter::start(3, || {
-        DbExecutor(SqliteConnection::establish("test.db").unwrap())
-    });
-
-    // Start http server
-    HttpServer::new(move || {
-        Application::with_state(State{db: addr.clone()})
-            .resource("/{name}", |r| r.method(Method::GET).a(index))})
-        .bind("127.0.0.1:8080").unwrap()
-        .start().unwrap();
-
-    println!("Started http server: 127.0.0.1:8080");
-    let _ = sys.run();
-}
-```
-
-And finally we can use address in a request handler. We get message response
-asynchronously, so handler needs to return future object, also `Route::a()` needs to be 
-used for async handler registration.
-
-
-```rust,ignore
-/// Async handler
-fn index(req: HttpRequest<State>) -> Box<Future<Item=HttpResponse, Error=Error>> {
-    let name = &req.match_info()["name"];
-
-    // Send message to `DbExecutor` actor
-    req.state().db.call_fut(CreateUser{name: name.to_owned()})
-        .from_err()
-        .and_then(|res| {
-            match res {
-                Ok(user) => Ok(httpcodes::HTTPOk.build().json(user)?),
-                Err(_) => Ok(httpcodes::HTTPInternalServerError.into())
-            }
-        })
-        .responder()

-# Getting Started
-
-Let’s create and run our first actix web application. We’ll create a new Cargo project
-that depends on actix web and then run the application.
-
-In previous section we already installed required rust version. Now let's create new cargo projects.
-
-## Hello, world! 
-
-Let’s write our first actix web application! Start by creating a new binary-based
-Cargo project and changing into the new directory:
-
-```bash
-cargo new hello-world --bin
-cd hello-world
-```
-
-Now, add actix and actix web as dependencies of your project by ensuring your Cargo.toml 
-contains the following:
-
-```toml
-[dependencies]
-actix = "0.4"
-actix-web = "0.3"
-```
-
-In order to implement a web server, first we need to create a request handler.
-
-A request handler is a function that accepts a `HttpRequest` instance as its only parameter 
-and returns a type that can be converted into `HttpResponse`:
-
-```rust
-# extern crate actix_web;
-# use actix_web::*;
-  fn index(req: HttpRequest) -> &'static str {
-      "Hello world!"
-  }
-# fn main() {}
-```
-
-Next, create an `Application` instance and register the
-request handler with the application's `resource` on a particular *HTTP method* and *path*::
-
-```rust
-# extern crate actix_web;
-# use actix_web::*;
-# fn index(req: HttpRequest) -> &'static str {
-#    "Hello world!"
-# }
-# fn main() {
-   Application::new()
-       .resource("/", |r| r.f(index));
-# }
-```
-
-After that, application instance can be used with `HttpServer` to listen for incoming
-connections. Server accepts function that should return `HttpHandler` instance:
-
-```rust,ignore
-   HttpServer::new(
-       || Application::new()
-           .resource("/", |r| r.f(index)))
-       .bind("127.0.0.1:8088")?
-       .run();
-```
-
-That's it. Now, compile and run the program with cargo run. 
-Head over to ``http://localhost:8088/`` to see the results.
-
-Here is full source of main.rs file:
-
-```rust
-# use std::thread;
-# extern crate actix_web;
-use actix_web::*;
-
-fn index(req: HttpRequest) -> &'static str {
-    "Hello world!"
-}
-
-fn main() {
-# thread::spawn(|| {
-    HttpServer::new(
-        || Application::new()
-            .resource("/", |r| r.f(index)))
-        .bind("127.0.0.1:8088").expect("Can not bind to 127.0.0.1:8088")
-        .run();
-# });
-}
-```
-
-Note on `actix` crate. Actix web framework is built on top of actix actor library. 
-`actix::System` initializes actor system, `HttpServer` is an actor and must run within
-properly configured actix system. For more information please check

-# Application
-
-Actix web provides some primitives to build web servers and applications with Rust.
-It provides routing, middlewares, pre-processing of requests, and post-processing of responses,
-websocket protocol handling, multipart streams, etc.
-
-All actix web server is built around `Application` instance.
-It is used for registering routes for resources, middlewares.
-Also it stores application specific state that is shared across all handlers
-within same application.
-
-Application acts as namespace for all routes, i.e all routes for specific application
-has same url path prefix. Application prefix always contains leading "/" slash. 
-If supplied prefix does not contain leading slash, it get inserted. 
-Prefix should consists of value path segments. i.e for application with prefix `/app` 
-any request with following paths `/app`, `/app/` or `/app/test` would match,
-but path `/application` would not match.
-
-```rust,ignore
-# extern crate actix_web;
-# extern crate tokio_core;
-# use actix_web::*;
-# fn index(req: HttpRequest) -> &'static str {
-#    "Hello world!"
-# }
-# fn main() {
-   let app = Application::new()
-       .prefix("/app")
-       .resource("/index.html", |r| r.method(Method::GET).f(index))
-       .finish()
-# }
-```
-
-In this example application with `/app` prefix and `index.html` resource
-get created. This resource is available as on `/app/index.html` url.
-For more information check 
-[*URL Matching*](./qs_5.html#using-a-application-prefix-to-compose-applications) section.
-
-Multiple applications could be served with one server:
-
-```rust
-# extern crate actix_web;
-# extern crate tokio_core;
-# use tokio_core::net::TcpStream;
-# use std::net::SocketAddr;
-use actix_web::*;
-
-fn main() {
-    HttpServer::<TcpStream, SocketAddr, _, _>::new(|| vec![
-        Application::new()
-            .prefix("/app1")
-            .resource("/", |r| r.f(|r| httpcodes::HTTPOk)),
-        Application::new()
-            .prefix("/app2")
-            .resource("/", |r| r.f(|r| httpcodes::HTTPOk)),
-        Application::new()
-            .resource("/", |r| r.f(|r| httpcodes::HTTPOk)),
-    ]);
-}
-```
-
-All `/app1` requests route to first application, `/app2` to second and then all other to third.
-Applications get matched based on registration order, if application with more general
-prefix is registered before less generic, that would effectively block less generic
-application to get matched. For example if *application* with prefix "/" get registered
-as first application, it would match all incoming requests.
-
-## State
-
-Application state is shared with all routes and resources within same application.
-State could be accessed with `HttpRequest::state()` method as a read-only item
-but interior mutability pattern with `RefCell` could be used to archive state mutability.
-State could be accessed with `HttpContext::state()` in case of http actor.
-State also available to route matching predicates and middlewares.
-
-Let's write simple application that uses shared state. We are going to store requests count
-in the state:
-
-```rust
-# extern crate actix;
-# extern crate actix_web;
-#
-use actix_web::*;
-use std::cell::Cell;
-
-// This struct represents state
-struct AppState {
-    counter: Cell<usize>,
-}
-
-fn index(req: HttpRequest<AppState>) -> String {
-    let count = req.state().counter.get() + 1; // <- get count
-    req.state().counter.set(count);            // <- store new count in state
-
-    format!("Request number: {}", count)       // <- response with count
-}
-
-fn main() {
-    Application::with_state(AppState{counter: Cell::new(0)})
-        .resource("/", |r| r.method(Method::GET).f(index))
-        .finish();
-}
-```
-
-Note on application state, http server accepts application factory rather than application
-instance. Http server construct application instance for each thread, so application state
-must be constructed multiple times. If you want to share state between different thread
-shared object should be used, like `Arc`. Application state does not need to be `Send` and `Sync`
-but application factory must be `Send` + `Sync`.

-## Multi-threading
-
-Http server automatically starts number of http workers, by default
-this number is equal to number of logical cpu in the system. This number
-could be overridden with `HttpServer::threads()` method.

-            .resource("/", |r| r.h(httpcodes::HTTPOk)))
-        .threads(4); // <- Start 4 workers
-}
-```
-
-Server create separate application instance for each created worker. Application state
-is not shared between threads, to share state `Arc` could be used. Application state
-does not need to be `Send` and `Sync` but application factory must be `Send` + `Sync`.
-
-## SSL
-
-There are two `tls` and `alpn` features for ssl server. `tls` feature is for `native-tls`
-integration and `alpn` is for `openssl`.
-
-```toml
-[dependencies]
-actix-web = { git = "https://github.com/actix/actix-web", features=["alpn"] }
-```
-
-```rust,ignore
-use std::fs::File;
-use actix_web::*;

-        .bind("127.0.0.1:8080").unwrap()
-        .serve_ssl(pkcs12).unwrap();
-}
-```
-
-Note on *HTTP/2.0* protocol over tls without prior knowledge, it requires
-[tls alpn](https://tools.ietf.org/html/rfc7301). At the moment only
-`openssl` has `alpn ` support.
-
-Please check [example](https://github.com/actix/actix-web/tree/master/examples/tls)
-for full example.
-
-## Keep-Alive
-
-Actix can wait for requests on a keep-alive connection. *Keep alive*
-connection behavior is defined by server settings.
-
- * `Some(75)` - enable 75 sec *keep alive* timer according request and response settings.
- * `Some(0)` - disable *keep alive*.
- * `None` - Use `SO_KEEPALIVE` socket option.
-
-```rust
-# extern crate actix_web;
-# extern crate tokio_core;
-# use tokio_core::net::TcpStream;
-# use std::net::SocketAddr;
-use actix_web::*;
-
-fn main() {
-    HttpServer::<TcpStream, SocketAddr, _, _>::new(||
-        Application::new()
-            .resource("/", |r| r.h(httpcodes::HTTPOk)))
-        .keep_alive(None); // <- Use `SO_KEEPALIVE` socket option.
-}
-```
-
-If first option is selected then *keep alive* state
-calculated based on response's *connection-type*. By default
-`HttpResponse::connection_type` is not defined in that case *keep alive*
-defined by request's http version. Keep alive is off for *HTTP/1.0*
-and is on for *HTTP/1.1* and "HTTP/2.0".
-
-*Connection type* could be change with `HttpResponseBuilder::connection_type()` method.
-
-```rust
-# extern crate actix_web;
-# use actix_web::httpcodes::*;
-use actix_web::*;
-
-fn index(req: HttpRequest) -> HttpResponse {
-    HTTPOk.build()
-        .connection_type(headers::ConnectionType::Close) // <- Close connection
-        .force_close()                                   // <- Alternative method
-        .finish().unwrap()
-}
-# fn main() {}
-```
-
-## Graceful shutdown
-
-Actix http server support graceful shutdown. After receiving a stop signal, workers
-have specific amount of time to finish serving requests. Workers still alive after the
-timeout are force dropped. By default shutdown timeout sets to 30 seconds.
-You can change this parameter with `HttpServer::shutdown_timeout()` method.
-
-You can send stop message to server with server address and specify if you what
-graceful shutdown or not. `start()` methods return address of the server.
-
-Http server handles several OS signals. *CTRL-C* is available on all OSs,
-other signals are available on unix systems.
-
-* *SIGINT* - Force shutdown workers
-* *SIGTERM* - Graceful shutdown workers
-* *SIGQUIT* - Force shutdown workers
-
-It is possible to disable signals handling with `HttpServer::disable_signals()` method.

-# Handler
-
-A request handler can by any object that implements 
-[*Handler trait*](../actix_web/dev/trait.Handler.html).
-Request handling happen in two stages. First handler object get called. 
-Handle can return any object that implements 
-[*Responder trait*](../actix_web/trait.Responder.html#foreign-impls).
-Then `respond_to()` get called on returned object. And finally
-result of the `respond_to()` call get converted to `Reply` object.
-
-By default actix provides `Responder` implementations for some standard types, 
-like `&'static str`, `String`, etc.
-For complete list of implementations check 
-[*Responder documentation*](../actix_web/trait.Responder.html#foreign-impls).
-
-Examples of valid handlers:

-```rust,ignore
-fn index(req: HttpRequest) -> &'static str {
-    "Hello world!"
-}

-Some notes on shared application state and handler state. If you noticed
-*Handler* trait is generic over *S*, which defines application state type. So
-application state is accessible from handler with `HttpRequest::state()` method. 
-But state is accessible as a read-only reference, if you need mutable access to state
-you have to implement it yourself. On other hand handler can mutable access it's own state
-as `handle` method takes mutable reference to *self*. Beware, actix creates multiple copies
-of application state and handlers, unique for each thread, so if you run your
-application in several threads actix will create same amount as number of threads 
-of application state objects and handler objects.
-
-Here is example of handler that stores number of processed requests:
-
-```rust
-# extern crate actix;
-# extern crate actix_web;
-use actix_web::*;
-use actix_web::dev::Handler;
-
-struct MyHandler(usize);
-
-impl<S> Handler<S> for MyHandler {
-    type Result = HttpResponse;
-
-    /// Handle request
-    fn handle(&mut self, req: HttpRequest<S>) -> Self::Result {
-        self.0 += 1;
-        httpcodes::HTTPOk.into()
-    }
-}
-# fn main() {}
-```
-
-This handler will work, but `self.0` value will be different depends on number of threads and
-number of requests processed per thread. Proper implementation would use `Arc` and `AtomicUsize`
-
-```rust
-# extern crate actix;
-# extern crate actix_web;
-use actix_web::*;
-use actix_web::dev::Handler;
-use std::sync::Arc;
-use std::sync::atomic::{AtomicUsize, Ordering};
-
-struct MyHandler(Arc<AtomicUsize>);
-
-impl<S> Handler<S> for MyHandler {
-    type Result = HttpResponse;
-
-    /// Handle request
-    fn handle(&mut self, req: HttpRequest<S>) -> Self::Result {
-        let num = self.0.load(Ordering::Relaxed) + 1;
-        self.0.store(num, Ordering::Relaxed);
-        httpcodes::HTTPOk.into()
-    }
-}
-
-fn main() {
-    let sys = actix::System::new("example");
-
-    let inc = Arc::new(AtomicUsize::new(0));
-
-    HttpServer::new(
-        move || { 
-            let cloned = inc.clone();
-            Application::new()
-                .resource("/", move |r| r.h(MyHandler(cloned)))
-        })
-        .bind("127.0.0.1:8088").unwrap()
-        .start();
-
-    println!("Started http server: 127.0.0.1:8088");
-#    actix::Arbiter::system().send(actix::msgs::SystemExit(0));
-    let _ = sys.run();
-}
-```
-
-Be careful with synchronization primitives like *Mutex* or *RwLock*. Actix web framework
-handles request asynchronously, by blocking thread execution all concurrent
-request handling processes would block. If you need to share or update some state 
-from multiple threads consider using [actix](https://actix.github.io/actix/actix/)  actor system.
-
-## Response with custom type
-
-To return custom type directly from handler function, type needs to implement `Responder` trait.
-Let's create response for custom type that serializes to `application/json` response:
-
-```rust
-# extern crate actix;
-# extern crate actix_web;
-extern crate serde;
-extern crate serde_json;
-#[macro_use] extern crate serde_derive;
-use actix_web::*;
-
-#[derive(Serialize)]
-struct MyObj {
-    name: &'static str,
-}
-
-/// Responder
-impl Responder for MyObj {
-    type Item = HttpResponse;
-    type Error = Error;
-
-    fn respond_to(self, req: HttpRequest) -> Result<HttpResponse> {
-        let body = serde_json::to_string(&self)?;
-
-        // Create response and set content type
-        Ok(HttpResponse::Ok()
-            .content_type("application/json")
-            .body(body)?)
-    }
-}
-
-/// Because `MyObj` implements `Responder`, it is possible to return it directly
-fn index(req: HttpRequest) -> MyObj {
-    MyObj{name: "user"}
-}
-
-fn main() {
-    let sys = actix::System::new("example");
-
-    HttpServer::new(
-        || Application::new()
-            .resource("/", |r| r.method(Method::GET).f(index)))
-        .bind("127.0.0.1:8088").unwrap()
-        .start();
-
-    println!("Started http server: 127.0.0.1:8088");
-#    actix::Arbiter::system().send(actix::msgs::SystemExit(0));
-    let _ = sys.run();
-}
-```
-
-## Async handlers
-
-There are two different types of async handlers. 
-
-Response object could be generated asynchronously or more precisely, any type
-that implements [*Responder*](../actix_web/trait.Responder.html) trait. In this case handle must
-return `Future` object that resolves to *Responder* type, i.e:
-
-```rust
-# extern crate actix_web;
-# extern crate futures;
-# extern crate bytes;
-# use actix_web::*;
-# use bytes::Bytes;
-# use futures::stream::once;
-# use futures::future::{FutureResult, result};
-fn index(req: HttpRequest) -> FutureResult<HttpResponse, Error> {
-
-    result(HttpResponse::Ok()
-           .content_type("text/html")
-           .body(format!("Hello!"))
-           .map_err(|e| e.into()))
-}
-
-fn index2(req: HttpRequest) -> FutureResult<&'static str, Error> {
-    result(Ok("Welcome!"))
-}
-
-fn main() {
-    Application::new()
-        .resource("/async", |r| r.route().a(index))
-        .resource("/", |r| r.route().a(index2))
-        .finish();
-}
-```
-
-Or response body can be generated asynchronously. In this case body
-must implement stream trait `Stream<Item=Bytes, Error=Error>`, i.e:
-
-```rust
-# extern crate actix_web;
-# extern crate futures;
-# extern crate bytes;
-# use actix_web::*;
-# use bytes::Bytes;
-# use futures::stream::once;
-fn index(req: HttpRequest) -> HttpResponse {
-    let body = once(Ok(Bytes::from_static(b"test")));
-
-    HttpResponse::Ok()
-       .content_type("application/json")
-       .body(Body::Streaming(Box::new(body))).unwrap()
-}
-
-fn main() {
-    Application::new()
-        .resource("/async", |r| r.f(index))
-        .finish();
-}
-```
-
-Both methods could be combined. (i.e Async response with streaming body)

-# Errors
-
-Actix uses [`Error` type](../actix_web/error/struct.Error.html) 
-and [`ResponseError` trait](../actix_web/error/trait.ResponseError.html) 
-for handling handler's errors.
-Any error that implements `ResponseError` trait can be returned as error value.
-*Handler* can return *Result* object, actix by default provides 
-`Responder` implementation for compatible result object. Here is implementation
-definition:
-
-```rust,ignore
-impl<T: Responder, E: Into<Error>> Responder for Result<T, E>
-```
-
-And any error that implements `ResponseError` can be converted into `Error` object.
-For example if *handler* function returns `io::Error`, it would be converted
-into `HTTPInternalServerError` response. Implementation for `io::Error` is provided 
-by default.
-
-```rust
-# extern crate actix_web;
-# use actix_web::*;
-use std::io;
-
-fn index(req: HttpRequest) -> io::Result<fs::NamedFile> {
-    Ok(fs::NamedFile::open("static/index.html")?)
-}
-#
-# fn main() {
-#     Application::new()
-#         .resource(r"/a/index.html", |r| r.f(index))
-#         .finish();
-# }
-```
-
-## Custom error response
-
-To add support for custom errors, all we need to do is just implement `ResponseError` trait
-for custom error. `ResponseError` trait has default implementation
-for `error_response()` method, it generates *500* response.
-
-```rust
-# extern crate actix_web;
-#[macro_use] extern crate failure;
-use actix_web::*;
-
-#[derive(Fail, Debug)]
-#[fail(display="my error")]
-struct MyError {
-   name: &'static str
-}
-
-/// Use default implementation for `error_response()` method
-impl error::ResponseError for MyError {}
-
-fn index(req: HttpRequest) -> Result<&'static str, MyError> {
-    Err(MyError{name: "test"})
-}
-#
-# fn main() {
-#     Application::new()
-#         .resource(r"/a/index.html", |r| r.f(index))
-#         .finish();
-# }
-```
-
-In this example *index* handler will always return *500* response. But it is easy
-to return different responses for different type of errors.
-
-```rust
-# extern crate actix_web;
-#[macro_use] extern crate failure;
-use actix_web::*;
-
-#[derive(Fail, Debug)]
-enum MyError {
-   #[fail(display="internal error")]
-   InternalError,
-   #[fail(display="bad request")]
-   BadClientData,
-   #[fail(display="timeout")]
-   Timeout,
-}
-
-impl error::ResponseError for MyError {
-    fn error_response(&self) -> HttpResponse {
-       match *self {
-          MyError::InternalError => HttpResponse::new(
-              StatusCode::INTERNAL_SERVER_ERROR, Body::Empty),
-          MyError::BadClientData => HttpResponse::new(
-              StatusCode::BAD_REQUEST, Body::Empty),
-          MyError::Timeout => HttpResponse::new(
-              StatusCode::GATEWAY_TIMEOUT, Body::Empty),
-       }
-    }
-}
-
-fn index(req: HttpRequest) -> Result<&'static str, MyError> {
-    Err(MyError::BadClientData)
-}
-#
-# fn main() {
-#     Application::new()
-#         .resource(r"/a/index.html", |r| r.f(index))
-#         .finish();
-# }
-```
-
-## Error helpers
-
-Actix provides set of error helper types. It is possible to use them to generate
-specific error response. We can use helper types for first example with custom error.
-
-```rust
-# extern crate actix_web;
-#[macro_use] extern crate failure;
-use actix_web::*;
-
-#[derive(Debug)]
-struct MyError {
-   name: &'static str
-}
-
-fn index(req: HttpRequest) -> Result<&'static str> {
-    let result: Result<&'static str, MyError> = Err(MyError{name: "test"});
-    
-    Ok(result.map_err(error::ErrorBadRequest)?)
-}
-# fn main() {
-#     Application::new()
-#         .resource(r"/a/index.html", |r| r.f(index))
-#         .finish();
-# }
-```
-
-In this example *BAD REQUEST* response get generated for `MyError` error.
-
-## Error logging
-
-Actix logs all errors with `WARN` log level. If log level set to `DEBUG`
-and `RUST_BACKTRACE` is enabled, backtrace get logged. The Error type uses
-cause's error backtrace if available, if the underlying failure does not provide
-a backtrace, a new backtrace is constructed pointing to that conversion point
-(rather than the origin of the error). This construction only happens if there
-is no underlying backtrace; if it does have a backtrace no new backtrace is constructed.
-
-You can enable backtrace and debug logging with following command: 
-
-```
->> RUST_BACKTRACE=1 RUST_LOG=actix_web=debug cargo run
-```

-# URL Dispatch
-
-URL dispatch provides a simple way to map URLs to `Handler` code using a simple pattern matching
-language. *Regex* crate and it's
-[*RegexSet*](https://doc.rust-lang.org/regex/regex/struct.RegexSet.html) is being used for
-pattern matching. If one of the patterns matches the path information associated with a request,
-a particular handler object is invoked. A handler is a specific object that implements
-`Handler` trait, defined in your application, that receives the request and returns
-a response object. More information is available in [handler section](../qs_4.html).
-
-## Resource configuration
-
-Resource configuration is the act of adding a new resource to an application.
-A resource has a name, which acts as an identifier to be used for URL generation.
-The name also allows developers to add routes to existing resources.
-A resource also has a pattern, meant to match against the *PATH* portion of a *URL*,
-it does not match against *QUERY* portion (the portion following the scheme and
-port, e.g., */foo/bar* in the *URL* *http://localhost:8080/foo/bar?q=value*).
-
-The [Application::resource](../actix_web/struct.Application.html#method.resource) methods
-add a single resource to application routing table. This method accepts *path pattern*
-and resource configuration function.
-
-```rust
-# extern crate actix_web;
-# use actix_web::*;
-# use actix_web::httpcodes::*;
-#
-# fn index(req: HttpRequest) -> HttpResponse {
-#   unimplemented!()
-# }
-#
-fn main() {
-    Application::new()
-        .resource("/prefix", |r| r.f(index))
-        .resource("/user/{name}",
-             |r| r.method(Method::GET).f(|req| HTTPOk))
-        .finish();
-}
-```
-
-*Configuration function* has following type:
-
-```rust,ignore
-   FnOnce(&mut Resource<_>) -> ()
-```
-
-*Configuration function* can set name and register specific routes.
-If resource does not contain any route or does not have any matching routes it
-returns *NOT FOUND* http resources.
-
-## Configuring a Route
-
-Resource contains set of routes. Each route in turn has set of predicates and handler.
-New route could be created with `Resource::route()` method which returns reference
-to new *Route* instance. By default *route* does not contain any predicates, so matches
-all requests and default handler is `HTTPNotFound`.
-
-Application routes incoming requests based on route criteria which is defined during
-resource registration and route registration. Resource matches all routes it contains in
-the order that the routes were registered via `Resource::route()`. *Route* can contain
-any number of *predicates* but only one handler.
-
-```rust
-# extern crate actix_web;
-# use actix_web::*;
-# use actix_web::httpcodes::*;
-
-fn main() {
-    Application::new()
-        .resource("/path", |resource|
-            resource.route()
-              .p(pred::Get())
-              .p(pred::Header("content-type", "text/plain"))
-              .f(|req| HTTPOk)
-        )
-        .finish();
-}
-```
-
-In this example `index` get called for *GET* request,
-if request contains `Content-Type` header and value of this header is *text/plain*
-and path equals to `/test`. Resource calls handle of the first matches route.
-If resource can not match any route "NOT FOUND" response get returned.
-
-[*Resource::route()*](../actix_web/struct.Resource.html#method.route) method returns
-[*Route*](../actix_web/struct.Route.html) object. Route can be configured with
-builder-like pattern. Following configuration methods are available:
-
-* [*Route::p()*](../actix_web/struct.Route.html#method.p) method registers new predicate,
-  any number of predicates could be registered for each route.
-
-* [*Route::f()*](../actix_web/struct.Route.html#method.f) method registers handler function
-  for this route. Only one handler could be registered. Usually handler registration
-  is the last config operation. Handler function could be function or closure and has type
-  `Fn(HttpRequest<S>) -> R + 'static`
-
-* [*Route::h()*](../actix_web/struct.Route.html#method.h) method registers handler object
-  that implements `Handler` trait. This is similar to `f()` method, only one handler could
-  be registered. Handler registration is the last config operation.
-
-* [*Route::a()*](../actix_web/struct.Route.html#method.a) method registers async handler
-  function for this route. Only one handler could be registered. Handler registration
-  is the last config operation. Handler function could be function or closure and has type
-  `Fn(HttpRequest<S>) -> Future<Item = HttpResponse, Error = Error> + 'static`
-
-## Route matching
-
-The main purpose of route configuration is to match (or not match) the request's `path`
-against a URL path pattern. `path` represents the path portion of the URL that was requested.
-
-The way that *actix* does this is very simple. When a request enters the system,
-for each resource configuration registration present in the system, actix checks
-the request's path against the pattern declared. *Regex* crate and it's
-[*RegexSet*](https://doc.rust-lang.org/regex/regex/struct.RegexSet.html) is being used for
-pattern matching. If resource could not be found, *default resource* get used as matched
-resource.
-
-When a route configuration is declared, it may contain route predicate arguments. All route
-predicates associated with a route declaration must be `true` for the route configuration to
-be used for a given request during a check. If any predicate in the set of route predicate
-arguments provided to a route configuration returns `false` during a check, that route is
-skipped and route matching continues through the ordered set of routes.
-
-If any route matches, the route matching process stops and the handler associated with
-route get invoked.
-
-If no route matches after all route patterns are exhausted, *NOT FOUND* response get returned.
-
-## Resource pattern syntax
-
-The syntax of the pattern matching language used by the actix in the pattern
-argument is straightforward.
-
-The pattern used in route configuration may start with a slash character. If the pattern
-does not start with a slash character, an implicit slash will be prepended
-to it at matching time. For example, the following patterns are equivalent:
-
-```
-{foo}/bar/baz
-```
-
-and:
-
-```
-/{foo}/bar/baz
-```
-
-A *variable part* (replacement marker) is specified in the form *{identifier}*,
-where this means "accept any characters up to the next slash character and use this
-as the name in the `HttpRequest.match_info()` object".
-
-A replacement marker in a pattern matches the regular expression `[^{}/]+`.
-
-A match_info is the `Params` object representing the dynamic parts extracted from a
-*URL* based on the routing pattern. It is available as *request.match_info*. For example, the
-following pattern defines one literal segment (foo) and two replacement markers (baz, and bar):
-
-```
-foo/{baz}/{bar}
-```
-
-The above pattern will match these URLs, generating the following match information:
-
-```
-foo/1/2        -> Params {'baz':'1', 'bar':'2'}
-foo/abc/def    -> Params {'baz':'abc', 'bar':'def'}
-```
-
-It will not match the following patterns however:
-
-```
-foo/1/2/        -> No match (trailing slash)
-bar/abc/def     -> First segment literal mismatch
-```
-
-The match for a segment replacement marker in a segment will be done only up to
-the first non-alphanumeric character in the segment in the pattern. So, for instance,
-if this route pattern was used:
-
-```
-foo/{name}.html
-```
-
-The literal path */foo/biz.html* will match the above route pattern, and the match result
-will be `Params{'name': 'biz'}`. However, the literal path */foo/biz* will not match,
-because it does not contain a literal *.html* at the end of the segment represented
-by *{name}.html* (it only contains biz, not biz.html).
-
-To capture both segments, two replacement markers can be used:
-
-```
-foo/{name}.{ext}
-```
-
-The literal path */foo/biz.html* will match the above route pattern, and the match
-result will be *Params{'name': 'biz', 'ext': 'html'}*. This occurs because there is a
-literal part of *.* (period) between the two replacement markers *{name}* and *{ext}*.
-
-Replacement markers can optionally specify a regular expression which will be used to decide
-whether a path segment should match the marker. To specify that a replacement marker should
-match only a specific set of characters as defined by a regular expression, you must use a
-slightly extended form of replacement marker syntax. Within braces, the replacement marker
-name must be followed by a colon, then directly thereafter, the regular expression. The default
-regular expression associated with a replacement marker *[^/]+* matches one or more characters
-which are not a slash. For example, under the hood, the replacement marker *{foo}* can more
-verbosely be spelled as *{foo:[^/]+}*. You can change this to be an arbitrary regular expression
-to match an arbitrary sequence of characters, such as *{foo:\d+}* to match only digits.
-
-Segments must contain at least one character in order to match a segment replacement marker.
-For example, for the URL */abc/*:
-
-* */abc/{foo}* will not match.
-* */{foo}/* will match.
-
-Note that path will be URL-unquoted and decoded into valid unicode string before
-matching pattern and values representing matched path segments will be URL-unquoted too.
-So for instance, the following pattern:
-
-```
-foo/{bar}
-```
-
-When matching the following URL:
-
-```
-http://example.com/foo/La%20Pe%C3%B1a
-```
-
-The matchdict will look like so (the value is URL-decoded):
-
-```
-Params{'bar': 'La Pe\xf1a'}
-```
-
-Literal strings in the path segment should represent the decoded value of the
-path provided to actix. You don't want to use a URL-encoded value in the pattern.
-For example, rather than this:
-
-```
-/Foo%20Bar/{baz}
-```
-
-You'll want to use something like this:
-
-```
-/Foo Bar/{baz}
-```
-
-It is possible to get "tail match". For this purpose custom regex has to be used.
-
-```
-foo/{bar}/{tail:.*}
-```
-
-The above pattern will match these URLs, generating the following match information:
-
-```
-foo/1/2/           -> Params{'bar':'1', 'tail': '2/'}
-foo/abc/def/a/b/c  -> Params{'bar':u'abc', 'tail': 'def/a/b/c'}
-```
-
-## Match information
-
-All values representing matched path segments are available in
-[`HttpRequest::match_info`](../actix_web/struct.HttpRequest.html#method.match_info).
-Specific value can be received with
-[`Params::get()`](../actix_web/dev/struct.Params.html#method.get) method.
-
-Any matched parameter can be deserialized into specific type if this type
-implements `FromParam` trait. For example most of standard integer types
-implements `FromParam` trait. i.e.:
-
-```rust
-# extern crate actix_web;
-use actix_web::*;
-
-fn index(req: HttpRequest) -> Result<String> {
-    let v1: u8 = req.match_info().query("v1")?;
-    let v2: u8 = req.match_info().query("v2")?;
-    Ok(format!("Values {} {}", v1, v2))
-}
-
-fn main() {
-    Application::new()
-        .resource(r"/a/{v1}/{v2}/", |r| r.f(index))
-        .finish();
-}
-```
-
-For this example for path '/a/1/2/', values v1 and v2 will resolve to "1" and "2".
-
-It is possible to create a `PathBuf` from a tail path parameter. The returned `PathBuf` is
-percent-decoded. If a segment is equal to "..", the previous segment (if
-any) is skipped.
-
-For security purposes, if a segment meets any of the following conditions,
-an `Err` is returned indicating the condition met:
-
-  * Decoded segment starts with any of: `.` (except `..`), `*`
-  * Decoded segment ends with any of: `:`, `>`, `<`
-  * Decoded segment contains any of: `/`
-  * On Windows, decoded segment contains any of: '\'
-  * Percent-encoding results in invalid UTF8.
-
-As a result of these conditions, a `PathBuf` parsed from request path parameter is
-safe to interpolate within, or use as a suffix of, a path without additional checks.
-
-```rust
-# extern crate actix_web;
-use actix_web::*;
-use std::path::PathBuf;
-
-fn index(req: HttpRequest) -> Result<String> {
-    let path: PathBuf = req.match_info().query("tail")?;
-    Ok(format!("Path {:?}", path))
-}
-
-fn main() {
-    Application::new()
-        .resource(r"/a/{tail:.*}", |r| r.method(Method::GET).f(index))
-        .finish();
-}
-```
-
-List of `FromParam` implementation could be found in
-[api docs](../actix_web/dev/trait.FromParam.html#foreign-impls)
-
-## Generating resource URLs
-
-Use the [HttpRequest.url_for()](../actix_web/struct.HttpRequest.html#method.url_for)
-method to generate URLs based on resource patterns. For example, if you've configured a
-resource with the name "foo" and the pattern "{a}/{b}/{c}", you might do this.
-
-```rust
-# extern crate actix_web;
-# use actix_web::*;
-# use actix_web::httpcodes::*;
-#
-fn index(req: HttpRequest) -> HttpResponse {
-    let url = req.url_for("foo", &["1", "2", "3"]); // <- generate url for "foo" resource
-    HTTPOk.into()
-}
-
-fn main() {
-    let app = Application::new()
-        .resource("/test/{a}/{b}/{c}", |r| {
-             r.name("foo");  // <- set resource name, then it could be used in `url_for`
-             r.method(Method::GET).f(|_| httpcodes::HTTPOk);
-        })
-        .finish();
-}
-```
-
-This would return something like the string *http://example.com/test/1/2/3* (at least if
-the current protocol and hostname implied http://example.com).
-`url_for()` method return [*Url object*](https://docs.rs/url/1.6.0/url/struct.Url.html) so you
-can modify this url (add query parameters, anchor, etc).
-`url_for()` could be called only for *named* resources otherwise error get returned.
-
-## External resources
-
-Resources that are valid URLs, could be registered as external resources. They are useful
-for URL generation purposes only and are never considered for matching at request time.
-
-```rust
-# extern crate actix_web;
-use actix_web::*;
-
-fn index(mut req: HttpRequest) -> Result<HttpResponse> {
-    let url = req.url_for("youtube", &["oHg5SJYRHA0"])?;
-    assert_eq!(url.as_str(), "https://youtube.com/watch/oHg5SJYRHA0");
-    Ok(httpcodes::HTTPOk.into())
-}
-
-fn main() {
-    let app = Application::new()
-        .resource("/index.html", |r| r.f(index))
-        .external_resource("youtube", "https://youtube.com/watch/{video_id}")
-        .finish();
-}
-```
-
-## Path normalization and redirecting to slash-appended routes
-
-By normalizing it means:
-
- - Add a trailing slash to the path.
- - Double slashes are replaced by one.
-
-The handler returns as soon as it finds a path that resolves
-correctly. The order if all enable is 1) merge, 3) both merge and append
-and 3) append. If the path resolves with
-at least one of those conditions, it will redirect to the new path.
-
-If *append* is *true* append slash when needed. If a resource is
-defined with trailing slash and the request comes without it, it will
-append it automatically.
-
-If *merge* is *true*, merge multiple consecutive slashes in the path into one.
-
-This handler designed to be use as a handler for application's *default resource*.
-
-```rust
-# extern crate actix_web;
-# #[macro_use] extern crate serde_derive;
-# use actix_web::*;
-#
-# fn index(req: HttpRequest) -> httpcodes::StaticResponse {
-#    httpcodes::HTTPOk
-# }
-fn main() {
-    let app = Application::new()
-        .resource("/resource/", |r| r.f(index))
-        .default_resource(|r| r.h(NormalizePath::default()))
-        .finish();
-}
-```
-
-In this example `/resource`, `//resource///` will be redirected to `/resource/` url.
-
-In this example path normalization handler get registered for all method,
-but you should not rely on this mechanism to redirect *POST* requests. The redirect of the
-slash-appending *Not Found* will turn a *POST* request into a GET, losing any
-*POST* data in the original request.
-
-It is possible to register path normalization only for *GET* requests only
-
-```rust
-# extern crate actix_web;
-# #[macro_use] extern crate serde_derive;
-# use actix_web::*;
-#
-# fn index(req: HttpRequest) -> httpcodes::StaticResponse {
-#    httpcodes::HTTPOk
-# }
-fn main() {
-    let app = Application::new()
-        .resource("/resource/", |r| r.f(index))
-        .default_resource(|r| r.method(Method::GET).h(NormalizePath::default()))
-        .finish();
-}
-```
-
-## Using a Application Prefix to Compose Applications
-
-The `Application::prefix()`" method allows to set specific application prefix.
-This prefix represents a resource prefix that will be prepended to all resource patterns added
-by the resource configuration. This can be used to help mount a set of routes at a different
-location than the included callable's author intended while still maintaining the same
-resource names.
-
-For example:
-
-```rust
-# extern crate actix_web;
-# use actix_web::*;
-#
-fn show_users(req: HttpRequest) -> HttpResponse {
-   unimplemented!()
-}
-
-fn main() {
-    Application::new()
-        .prefix("/users")
-        .resource("/show", |r| r.f(show_users))
-        .finish();
-}
-```
-
-In the above example, the *show_users* route will have an effective route pattern of
-*/users/show* instead of */show* because the application's prefix argument will be prepended
-to the pattern. The route will then only match if the URL path is */users/show*,
-and when the `HttpRequest.url_for()` function is called with the route name show_users,
-it will generate a URL with that same path.
-
-## Custom route predicates
-
-You can think of predicate as simple function that accept *request* object reference
-and returns *true* or *false*. Formally predicate is any object that implements
-[`Predicate`](../actix_web/pred/trait.Predicate.html) trait. Actix provides
-several predicates, you can check [functions section](../actix_web/pred/index.html#functions)
-of api docs.
-
-Here is simple predicates that check that request contains specific *header*:
-
-```rust
-# extern crate actix_web;
-# extern crate http;
-# use actix_web::*;
-# use actix_web::httpcodes::*;
-use http::header::CONTENT_TYPE;
-use actix_web::pred::Predicate;
-
-struct ContentTypeHeader;
-
-impl<S: 'static> Predicate<S> for ContentTypeHeader {
-
-    fn check(&self, req: &mut HttpRequest<S>) -> bool {
-       req.headers().contains_key(CONTENT_TYPE)
-    }
-}
-
-fn main() {
-    Application::new()
-        .resource("/index.html", |r|
-           r.route()
-              .p(ContentTypeHeader)
-              .h(HTTPOk));
-}
-```
-
-In this example *index* handler will be called only if request contains *CONTENT-TYPE* header.
-
-Predicates can have access to application's state via `HttpRequest::state()` method.
-Also predicates can store extra information in
-[requests`s extensions](../actix_web/struct.HttpRequest.html#method.extensions).
-
-### Modifying predicate values
-
-You can invert the meaning of any predicate value by wrapping it in a `Not` predicate.
-For example if you want to return "METHOD NOT ALLOWED" response for all methods
-except "GET":
-
-```rust
-# extern crate actix_web;
-# extern crate http;
-# use actix_web::*;
-# use actix_web::httpcodes::*;
-use actix_web::pred;
-
-fn main() {
-    Application::new()
-        .resource("/index.html", |r|
-           r.route()
-              .p(pred::Not(pred::Get()))
-              .f(|req| HTTPMethodNotAllowed))
-        .finish();
-}
-```
-
-`Any` predicate accept list of predicates and matches if any of the supplied
-predicates match. i.e:
-
-```rust,ignore
-    pred::Any(pred::Get()).or(pred::Post())
-```
-
-`All` predicate accept list of predicates and matches if all of the supplied
-predicates match. i.e:
-
-```rust,ignore
-    pred::All(pred::Get()).and(pred::Header("content-type", "plain/text"))
-```
-
-## Changing the default Not Found response
-
-If path pattern can not be found in routing table or resource can not find matching
-route, default resource is used. Default response is *NOT FOUND* response.
-It is possible to override *NOT FOUND* response with `Application::default_resource()` method.
-This method accepts *configuration function* same as normal resource configuration
-with `Application::resource()` method.
-
-```rust
-# extern crate actix_web;
-# extern crate http;
-use actix_web::*;
-use actix_web::httpcodes::*;
-
-fn main() {
-    Application::new()
-        .default_resource(|r| {
-              r.method(Method::GET).f(|req| HTTPNotFound);
-              r.route().p(pred::Not(pred::Get())).f(|req| HTTPMethodNotAllowed);
-         })
-#        .finish();
-}
-```

-# Request & Response
-
-## Response
-
-Builder-like patter is used to construct an instance of `HttpResponse`.
-`HttpResponse` provides several method that returns `HttpResponseBuilder` instance,
-which is implements various convenience methods that helps build response.
-Check [documentation](../actix_web/dev/struct.HttpResponseBuilder.html)
-for type description. Methods `.body`, `.finish`, `.json` finalizes response creation and
-returns constructed *HttpResponse* instance. if this methods get called for the same
-builder instance multiple times, builder will panic.
-
-```rust
-# extern crate actix_web;
-use actix_web::*;
-use actix_web::headers::ContentEncoding;
-
-fn index(req: HttpRequest) -> HttpResponse {
-    HttpResponse::Ok()
-        .content_encoding(ContentEncoding::Br)
-        .content_type("plain/text")
-        .header("X-Hdr", "sample")
-        .body("data").unwrap()
-}
-# fn main() {}
-```
-
-## Content encoding
-
-Actix automatically *compress*/*decompress* payload. Following codecs are supported: 
-
- * Brotli
- * Gzip
- * Deflate
- * Identity
- 
- If request headers contains `Content-Encoding` header, request payload get decompressed
- according to header value. Multiple codecs are not supported, i.e: `Content-Encoding: br, gzip`.
- 
-Response payload get compressed based on *content_encoding* parameter. 
-By default `ContentEncoding::Auto` is used. If `ContentEncoding::Auto` is selected
-then compression depends on request's `Accept-Encoding` header. 
-`ContentEncoding::Identity` could be used to disable compression.
-If other content encoding is selected the compression is enforced for this codec. For example,
-to enable `brotli` response's body compression use `ContentEncoding::Br`:
-
-```rust
-# extern crate actix_web;
-use actix_web::*;
-use actix_web::headers::ContentEncoding;
-
-fn index(req: HttpRequest) -> HttpResponse {
-    HttpResponse::Ok()
-        .content_encoding(ContentEncoding::Br)
-        .body("data").unwrap()
-}
-# fn main() {}
-```
-
-
-## JSON Request
-
-There are two options of json body deserialization. 
-
-First option is to use *HttpResponse::json()* method. This method returns
-[*JsonBody*](../actix_web/dev/struct.JsonBody.html) object which resolves into 
-deserialized value.
-
-```rust
-# extern crate actix;
-# extern crate actix_web;
-# extern crate futures;
-# extern crate serde_json;
-# #[macro_use] extern crate serde_derive;
-# use actix_web::*;
-# use futures::Future;
-#[derive(Debug, Serialize, Deserialize)]
-struct MyObj {
-    name: String,
-    number: i32,
-}
-
-fn index(mut req: HttpRequest) -> Box<Future<Item=HttpResponse, Error=Error>> {
-    req.json().from_err()
-        .and_then(|val: MyObj| {
-            println!("model: {:?}", val);
-            Ok(httpcodes::HTTPOk.build().json(val)?)  // <- send response
-        })
-        .responder()
-}
-# fn main() {}
-```
-
-Or you can manually load payload into memory and then deserialize it.
-Here is simple example. We will deserialize *MyObj* struct. We need to load request
-body first and then deserialize json into object.
-
-```rust
-# extern crate actix_web;
-# extern crate futures;
-# use actix_web::*;
-# #[macro_use] extern crate serde_derive;
-extern crate serde_json;
-use futures::{Future, Stream};
-
-#[derive(Serialize, Deserialize)]
-struct MyObj {name: String, number: i32}
-
-fn index(mut req: HttpRequest) -> Box<Future<Item=HttpResponse, Error=Error>> {
-   // `concat2` will asynchronously read each chunk of the request body and
-   // return a single, concatenated, chunk
-   req.payload_mut().readany().concat2()
-      // `Future::from_err` acts like `?` in that it coerces the error type from
-      // the future into the final error type
-      .from_err()
-      // `Future::and_then` can be used to merge an asynchronous workflow with a
-      // synchronous workflow
-      .and_then(|body| {                           // <- body is loaded, now we can deserialize json
-          let obj = serde_json::from_slice::<MyObj>(&body)?;
-          Ok(httpcodes::HTTPOk.build().json(obj)?) // <- send response
-      })
-      .responder()
-}
-# fn main() {}
-```
-
-Complete example for both options is available in 
-[examples directory](https://github.com/actix/actix-web/tree/master/examples/json/).
-
-
-## JSON Response
-
-The `Json` type allows you to respond with well-formed JSON data: simply return a value of 
-type Json<T> where T is the type of a structure to serialize into *JSON*. The 
-type `T` must implement the `Serialize` trait from *serde*.
-
-```rust
-# extern crate actix_web;
-#[macro_use] extern crate serde_derive;
-use actix_web::*;
-
-#[derive(Serialize)]
-struct MyObj {
-    name: String,
-}
-
-fn index(req: HttpRequest) -> Result<Json<MyObj>> {
-    Ok(Json(MyObj{name: req.match_info().query("name")?}))
-}
-
-fn main() {
-    Application::new()
-        .resource(r"/a/{name}", |r| r.method(Method::GET).f(index))
-        .finish();
-}
-```
-
-## Chunked transfer encoding
-
-Actix automatically decode *chunked* encoding. `HttpRequest::payload()` already contains
-decoded bytes stream. If request payload compressed with one of supported
-compression codecs (br, gzip, deflate) bytes stream get decompressed.
-
-Chunked encoding on response could be enabled with `HttpResponseBuilder::chunked()` method.
-But this takes effect only for `Body::Streaming(BodyStream)` or `Body::StreamingContext` bodies.
-Also if response payload compression is enabled and streaming body is used, chunked encoding
-get enabled automatically.
-
-Enabling chunked encoding for *HTTP/2.0* responses is forbidden.
-
-```rust
-# extern crate actix_web;
-use actix_web::*;
-
-fn index(req: HttpRequest) -> HttpResponse {
-    HttpResponse::Ok()
-        .chunked()
-        .body(Body::Streaming(payload::Payload::empty().stream())).unwrap()
-}
-# fn main() {}
-```
-
-## Multipart body
-
-Actix provides multipart stream support. 
-[*Multipart*](../actix_web/multipart/struct.Multipart.html) is implemented as 
-a stream of multipart items, each item could be
-[*Field*](../actix_web/multipart/struct.Field.html) or nested *Multipart* stream.
-`HttpResponse::multipart()` method returns *Multipart* stream for current request.
-
-In simple form multipart stream handling could be implemented similar to this example
-
-```rust,ignore
-# extern crate actix_web;
-use actix_web::*;
-
-fn index(req: HttpRequest) -> Box<Future<...>> {
-    req.multipart()        // <- get multipart stream for current request
-       .and_then(|item| {  // <- iterate over multipart items
-           match item {
-                           // Handle multipart Field
-              multipart::MultipartItem::Field(field) => {
-                 println!("==== FIELD ==== {:?} {:?}", field.headers(), field.content_type());
-                 
-                 Either::A(
-                           // Field in turn is a stream of *Bytes* objects
-                   field.map(|chunk| {
-                        println!("-- CHUNK: \n{}",
-                                 std::str::from_utf8(&chunk).unwrap());})
-                      .fold((), |_, _| result(Ok(()))))
-                },
-              multipart::MultipartItem::Nested(mp) => {
-                         // Or item could be nested Multipart stream 
-                 Either::B(result(Ok(())))
-              }
-         }
-   })
-}
-```
-
-Full example is available in 
-[examples directory](https://github.com/actix/actix-web/tree/master/examples/multipart/).
-
-## Urlencoded body
-
-Actix provides support for *application/x-www-form-urlencoded* encoded body.
-`HttpResponse::urlencoded()` method returns
-[*UrlEncoded*](../actix_web/dev/struct.UrlEncoded.html) future, it resolves 
-into `HashMap<String, String>` which contains decoded parameters.
-*UrlEncoded* future can resolve into a error in several cases:
-
-* content type is not `application/x-www-form-urlencoded`
-* transfer encoding is `chunked`.
-* content-length is greater than 256k
-* payload terminates with error.
-
-
-```rust
-# extern crate actix_web;
-# extern crate futures;
-use actix_web::*;
-use futures::future::{Future, ok};
-
-fn index(mut req: HttpRequest) -> Box<Future<Item=HttpResponse, Error=Error>> {
-    req.urlencoded()         // <- get UrlEncoded future
-       .from_err()
-       .and_then(|params| {  // <- url encoded parameters
-             println!("==== BODY ==== {:?}", params);
-             ok(httpcodes::HTTPOk.into())
-       })
-       .responder()
-}
-# fn main() {}
-```
-
-
-## Streaming request
-
-Actix uses [*Payload*](../actix_web/payload/struct.Payload.html) object as request payload stream.
-*HttpRequest* provides several methods, which can be used for payload access.
-At the same time *Payload* implements *Stream* trait, so it could be used with various
-stream combinators. Also *Payload* provides several convenience methods that return
-future object that resolve to Bytes object.
-
-* *readany()* method returns *Stream* of *Bytes* objects.
-
-* *readexactly()* method returns *Future* that resolves when specified number of bytes
-  get received.
-  
-* *readline()* method returns *Future* that resolves when `\n` get received.
-
-* *readuntil()* method returns *Future* that resolves when specified bytes string
-  matches in input bytes stream
-
-In this example handle reads request payload chunk by chunk and prints every chunk.
-
-```rust
-# extern crate actix_web;
-# extern crate futures;
-# use futures::future::result;
-use actix_web::*;
-use futures::{Future, Stream};
-
-
-fn index(mut req: HttpRequest) -> Box<Future<Item=HttpResponse, Error=Error>> {
-    req.payload()
-       .readany()
-       .from_err()
-       .fold((), |_, chunk| {
-            println!("Chunk: {:?}", chunk);
-            result::<_, error::PayloadError>(Ok(()))
-        })
-       .map(|_| HttpResponse::Ok().finish().unwrap())
-       .responder()
-}
-# fn main() {}

-# Testing
-
-Every application should be well tested and. Actix provides the tools to perform unit and
-integration tests.
-
-## Unit tests
-
-For unit testing actix provides request builder type and simple handler runner.
-[*TestRequest*](../actix_web/test/struct.TestRequest.html) implements builder-like pattern.
-You can generate `HttpRequest` instance with `finish()` method or you can
-run your handler with `run()` or `run_async()` methods.
-
-```rust
-# extern crate http;
-# extern crate actix_web;
-use http::{header, StatusCode};
-use actix_web::*;
-use actix_web::test::TestRequest;
-
-fn index(req: HttpRequest) -> HttpResponse {
-     if let Some(hdr) = req.headers().get(header::CONTENT_TYPE) {
-        if let Ok(s) = hdr.to_str() {
-            return httpcodes::HTTPOk.into()
-        }
-     }
-     httpcodes::HTTPBadRequest.into()

-fn main() {

-        .run(index)
-        .unwrap();
-    assert_eq!(resp.status(), StatusCode::BAD_REQUEST);
-}
-```
-
-
-## Integration tests
-
-There are several methods how you can test your application. Actix provides 
-[*TestServer*](../actix_web/test/struct.TestServer.html)
-server that could be used to run whole application of just specific handlers
-in real http server. At the moment it is required to use third-party libraries
-to make actual requests, libraries like [reqwest](https://crates.io/crates/reqwest).
-
-In simple form *TestServer* could be configured to use handler. *TestServer::new* method
-accepts configuration function, only argument for this function is *test application*
-instance. You can check [api documentation](../actix_web/test/struct.TestApp.html)
-for more information.
-
-```rust
-# extern crate actix_web;
-extern crate reqwest;
-use actix_web::*;
-use actix_web::test::TestServer;
-
-fn index(req: HttpRequest) -> HttpResponse {
-     httpcodes::HTTPOk.into()
-}
-
-fn main() {
-    let srv = TestServer::new(|app| app.handler(index));        // <- Start new test server
-    let url = srv.url("/");                                     // <- get handler url
-    assert!(reqwest::get(&url).unwrap().status().is_success()); // <- make request
-}
-```
-
-Other option is to use application factory. In this case you need to pass factory function
-same as you use for real http server configuration.
-
-```rust
-# extern crate actix_web;
-extern crate reqwest;
-use actix_web::*;
-use actix_web::test::TestServer;
-
-fn index(req: HttpRequest) -> HttpResponse {
-     httpcodes::HTTPOk.into()
-}
-
-/// This function get called by http server.
-fn create_app() -> Application {
-    Application::new()
-        .resource("/test", |r| r.h(index))
-}
-
-fn main() {
-    let srv = TestServer::with_factory(create_app);             // <- Start new test server
-    let url = srv.url("/test");                                 // <- get handler url
-    assert!(reqwest::get(&url).unwrap().status().is_success()); // <- make request

-# WebSockets
-
-Actix supports WebSockets out-of-the-box. It is possible to convert request's `Payload`
-to a stream of [*ws::Message*](../actix_web/ws/enum.Message.html) with 
-a [*ws::WsStream*](../actix_web/ws/struct.WsStream.html) and then use stream
-combinators to handle actual messages. But it is simpler to handle websocket communications
-with http actor.
-
-This is example of simple websocket echo server:
-
-```rust
-# extern crate actix;
-# extern crate actix_web;
-use actix::*;
-use actix_web::*;
-
-/// Define http actor
-struct Ws;
-
-impl Actor for Ws {
-    type Context = ws::WebsocketContext<Self>;
-}
-
-/// Define Handler for ws::Message message
-impl Handler<ws::Message> for Ws {
-    type Result=();
-

-/// Path normalization helper
+/// Access an application state
 ///
-/// By normalizing it means:
+/// `S` - application state type
 ///
-/// - Add a trailing slash to the path.
-/// - Double slashes are replaced by one.
-///
-/// The handler returns as soon as it finds a path that resolves
-/// correctly. The order if all enable is 1) merge, 3) both merge and append
-/// and 3) append. If the path resolves with
-/// at least one of those conditions, it will redirect to the new path.
-///
-/// If *append* is *true* append slash when needed. If a resource is
-/// defined with trailing slash and the request comes without it, it will
-/// append it automatically.
-///
-/// If *merge* is *true*, merge multiple consecutive slashes in the path into one.
-///
-/// This handler designed to be use as a handler for application's *default resource*.
+/// ## Example
 ///
 /// ```rust
+/// # extern crate bytes;
 /// # extern crate actix_web;
-/// # #[macro_use] extern crate serde_derive;
-/// # use actix_web::*;
-/// #
-/// # fn index(req: HttpRequest) -> httpcodes::StaticResponse {
-/// #     httpcodes::HTTPOk
-/// # }
+/// # extern crate futures;
+/// #[macro_use] extern crate serde_derive;
+/// use actix_web::{http, App, Path, State};
+///
+/// /// Application state
+/// struct MyApp {
+///     msg: &'static str,
+/// }
+///
+/// #[derive(Deserialize)]
+/// struct Info {
+///     username: String,
+/// }
+///
+/// /// extract path info using serde
+/// fn index(state: State<MyApp>, path: Path<Info>) -> String {
+///     format!("{} {}!", state.msg, path.username)
+/// }
+///
 /// fn main() {
-///     let app = Application::new()
-///         .resource("/test/", |r| r.f(index))
-///         .default_resource(|r| r.h(NormalizePath::default()))
-///         .finish();
+///     let app = App::with_state(MyApp { msg: "Welcome" }).resource(
+///         "/{username}/index.html", // <- define path parameters
+///         |r| r.method(http::Method::GET).with(index),
+///     ); // <- use `with` extractor
 /// }
 /// ```
-/// In this example `/test`, `/test///` will be redirected to `/test/` url.
