+* `HttpServer::listen_tls()`, `HttpServer::listen_ssl()`, `HttpServer::listen_rustls()` have been
+  deprecated in favor of `HttpServer::listen_with()` with specific `acceptor`.
+
+* `HttpServer::bind_tls()`, `HttpServer::bind_ssl()`, `HttpServer::bind_rustls()` have been
+  deprecated in favor of `HttpServer::bind_with()` with specific `acceptor`.

-//! Http server
-use std::net::Shutdown;
+//! Http server module
+//!
+//! The module contains everything necessary to setup
+//! HTTP server.
+//!
+//! In order to start HTTP server, first you need to create and configure it
+//! using factory that can be supplied to [new](fn.new.html).
+//!
+//! ## Factory
+//!
+//! Factory is a function that returns Application, describing how
+//! to serve incoming HTTP requests.
+//!
+//! As the server uses worker pool, the factory function is restricted to trait bounds
+//! `Send + Clone + 'static` so that each worker would be able to accept Application
+//! without a need for synchronization.
+//!
+//! If you wish to share part of state among all workers you should
+//! wrap it in `Arc` and potentially synchronization primitive like
+//! [RwLock](https://doc.rust-lang.org/std/sync/struct.RwLock.html)
+//! If the wrapped type is not thread safe.
+//!
+//! Note though that locking is not advisable for asynchronous programming
+//! and you should minimize all locks in your request handlers
+//!
+//! ## HTTPS Support
+//!
+//! Actix-web provides support for major crates that provides TLS.
+//! Each TLS implementation is provided with [AcceptorService](trait.AcceptorService.html)
+//! that describes how HTTP Server accepts connections.
+//!
+//! For `bind` and `listen` there are corresponding `bind_ssl|tls|rustls` and `listen_ssl|tls|rustls` that accepts
+//! these services.
+//!
+//! **NOTE:** `native-tls` doesn't support `HTTP2` yet
+//!
+//! ## Signal handling and shutdown
+//!
+//! By default HTTP Server listens for system signals
+//! and, gracefully shuts down at most after 30 seconds.
+//!
+//! Both signal handling and shutdown timeout can be controlled
+//! using corresponding methods.
+//!
+//! If worker, for some reason, unable to shut down within timeout
+//! it is forcibly dropped.
+//!
+//! ## Example
+//!
+//! ```rust,ignore
+//!extern crate actix;
+//!extern crate actix_web;
+//!extern crate rustls;
+//!
+//!use actix_web::{http, middleware, server, App, Error, HttpRequest, HttpResponse, Responder};

+//!use rustls::{NoClientAuth, ServerConfig};
+//!
+//!fn index(req: &HttpRequest) -> Result<HttpResponse, Error> {
+//!    Ok(HttpResponse::Ok().content_type("text/plain").body("Welcome!"))
+//!}
+//!
+//!fn load_ssl() -> ServerConfig {
+//!    use std::io::BufReader;
+//!
+//!    const CERT: &'static [u8] = include_bytes!("../cert.pem");
+//!    const KEY: &'static [u8] = include_bytes!("../key.pem");
