+//! A filter for cross-site request forgery (CSRF).
+//!
+//! This middleware is stateless and [based on request
+//! headers](https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)_Prevention_Cheat_Sheet#Verifying_Same_Origin_with_Standard_Headers).
+//!
+//! By default requests are allowed only if one of these is true:
+//!
+//! * The request method is safe (`GET`, `HEAD`, `OPTIONS`). It is the
+//!   applications responsibility to ensure these methods cannot be used to
+//!   execute unwanted actions. Note that upgrade requests for websockets are
+//!   also considered safe.
+//! * The `Origin` header (added automatically by the browser) matches one
+//!   of the allowed origins.
+//! * There is no `Origin` header but the `Referer` header matches one of
+//!   the allowed origins.
+//!
+//! Use [`CsrfFilterBuilder::allow_xhr()`](struct.CsrfFilterBuilder.html#method.allow_xhr)
+//! if you want to allow requests with unsafe methods via
+//! [CORS](../cors/struct.Cors.html).
+//!
+//! # Example
+//!
+//! ```
+//! # extern crate actix_web;
+//! # use actix_web::*;
+//!
+//! use actix_web::middleware::csrf;
+//!
+//! fn handle_post(_req: HttpRequest) -> &'static str {
+//!     "This action should only be triggered with requests from the same site"
+//! }
+//!
+//! fn main() {
+//!     let app = Application::new()
+//!         .middleware(
+//!             csrf::CsrfFilter::build()
+//!                 .allowed_origin("https://www.example.com")
