<commit_before>//! User sessions.
//!
//! Actix provides a general solution for session management. Session
//! middlewares could provide different implementations which could
//! be accessed via general session api.
//!
//! By default, only cookie session backend is implemented. Other
//! backend implementations can be added.
//!
//! In general, you insert a *session* middleware and initialize it
//! , such as a `CookieSessionBackend`. To access session data,
//! [*Session*](struct.Session.html) extractor must be used. Session
//! extractor allows us to get or set session data.
//!
//! ```rust
//! use actix_web::{web, App, HttpServer, HttpResponse, Error};
//! use actix_session::{Session, CookieSession};
//!
//! fn index(session: Session) -> Result<&'static str, Error> {
//!     // access session data
//!     if let Some(count) = session.get::<i32>("counter")? {
//!         println!("SESSION value: {}", count);
//!         session.set("counter", count+1)?;
//!     } else {
//!         session.set("counter", 1)?;
//!     }
//!
//!     Ok("Welcome!")
//! }
//!
//! fn main() -> std::io::Result<()> {
//! # std::thread::spawn(||
//!     HttpServer::new(
//!         || App::new().wrap(
//!               CookieSession::signed(&[0; 32]) // <- create cookie based session middleware
//!                     .secure(false)
//!              )
//!             .service(web::resource("/").to(|| HttpResponse::Ok())))
//!         .bind("127.0.0.1:59880")?
//!         .run()
//! # );
//! # Ok(())

<commit_msg>Guard cookie mod by cookie-session feature (#883)<commit_after>//! User sessions.
//!
//! Actix provides a general solution for session management. Session
//! middlewares could provide different implementations which could
//! be accessed via general session api.
//!
//! By default, only cookie session backend is implemented. Other
//! backend implementations can be added.
//!
//! In general, you insert a *session* middleware and initialize it
//! , such as a `CookieSessionBackend`. To access session data,
//! [*Session*](struct.Session.html) extractor must be used. Session
//! extractor allows us to get or set session data.
//!
//! ```rust
//! use actix_web::{web, App, HttpServer, HttpResponse, Error};
//! use actix_session::{Session, CookieSession};
//!
//! fn index(session: Session) -> Result<&'static str, Error> {
//!     // access session data
//!     if let Some(count) = session.get::<i32>("counter")? {
//!         println!("SESSION value: {}", count);
//!         session.set("counter", count+1)?;
//!     } else {
//!         session.set("counter", 1)?;
//!     }
//!
//!     Ok("Welcome!")
//! }
//!
//! fn main() -> std::io::Result<()> {
//! # std::thread::spawn(||
//!     HttpServer::new(
//!         || App::new().wrap(
//!               CookieSession::signed(&[0; 32]) // <- create cookie based session middleware
//!                     .secure(false)
//!              )
//!             .service(web::resource("/").to(|| HttpResponse::Ok())))
//!         .bind("127.0.0.1:59880")?
//!         .run()
//! # );
//! # Ok(())
//! }
