backend—we do not want to store session states indefinitely, otherwise we will
inevitably run out of storage by holding on to the state of countless abandoned or
expired sessions!</p>
<p>We are dealing with the lifecycle of two uncorrelated object here: the session cookie
and the session state. It is not a big issue if the session state outlives the cookie—
we are wasting some space in the backend storage, but it will be cleaned up eventually.
What happens, instead, if the cookie outlives the session state? A new session starts—
e.g. if sessions are being used for authentication, the user is de-facto logged out.</p>
<p>It is not possible to predict with certainty how long a browser session is going to
last—you need to provide a reasonable upper bound. You do so via <code>state_ttl</code>—it dictates
what TTL should be used for session state when the lifecycle of the session cookie is
tied to the browser session length. <a href="struct.SessionMiddleware.html" title="SessionMiddleware"><code>SessionMiddleware</code></a> will default to 1 day if
<code>state_ttl</code> is left unspecified.</p>
</div></div></div><div class="docblock"><p>The session cookie will expire when the current browser session ends.</p>
<p>When does a browser session end? It depends on the browser! Chrome, for example, will often
continue running in the background when the browser is closed—session cookies are not
deleted and they will still be available when the browser is opened again. Check the
documentation of the browser you are targeting for up-to-date information.</p>

<p>Provides a general solution for session management. Session middleware could provide different
implementations which could be accessed via general session API.</p>
<p>This crate provides a general solution for session management and includes a cookie backend.
Other backend implementations can be built to use persistent or key-value stores, for example.</p>
<p>In general, some session middleware, such as a <a href="struct.CookieSession.html" title="CookieSession"><code>CookieSession</code></a> is initialized and applied.
To access session data, the <a href="struct.Session.html" title="Session"><code>Session</code></a> extractor must be used. This extractor allows reading
modifying session data.</p>

<p>The HTTP protocol, at a first glance, is stateless: the client sends a request, the server
parses its content, performs some processing and returns a response. The outcome is only
influenced by the provided inputs (i.e. the request content) and whatever state the server
queries while performing its processing.</p>
<p>Stateless systems are easier to reason about, but they are not quite as powerful as we need to
be - e.g. how do you authenticate a user? The user would be forced to authenticate <strong>for every
single request</strong>. That is, for example, how Basic Authentication works. While it may work for
a machine user (i.e. an API client), it is impractical for a person—you do not want a login
prompt on every single page you navigate to!</p>
<p>There is a solution - <strong>sessions</strong>. Using sessions the server can attach state to a set of
requests coming from the same client. They are built on top of cookies - the server sets a
cookie in the HTTP response (<code>Set-Cookie</code> header), the client (e.g. the browser) will store the
cookie and play it back to the server when sending new requests (using the <code>Cookie</code> header).</p>
<p>We refer to the cookie used for sessions as a <strong>session cookie</strong>. Its content is called
<strong>session key</strong> (or <strong>session ID</strong>), while the state attached to the session is referred to as
<strong>session state</strong>.</p>
<p><code>actix-session</code> provides an easy-to-use framework to manage sessions in applications built on
top of Actix Web. <a href="struct.SessionMiddleware.html" title="SessionMiddleware"><code>SessionMiddleware</code></a> is the middleware underpinning the functionality
provided by <code>actix-session</code>; it takes care of all the session cookie handling and instructs the
<strong>storage backend</strong> to create/delete/update the session state based on the operations performed
against the active <a href="struct.Session.html" title="Session"><code>Session</code></a>.</p>
<p><code>actix-session</code> provides some built-in storage backends: (<a href="storage/struct.CookieSessionStore.html" title="storage::CookieSessionStore"><code>storage::CookieSessionStore</code></a>,
<a href="storage/struct.RedisSessionStore.html" title="storage::RedisSessionStore"><code>storage::RedisSessionStore</code></a>, and <a href="storage/struct.RedisActorSessionStore.html" title="storage::RedisActorSessionStore"><code>storage::RedisActorSessionStore</code></a>) - you can create a
custom storage backend by implementing the <a href="storage/trait.SessionStore.html"><code>SessionStore</code></a> trait.</p>
<p>Further reading on sessions:</p>

<h2 id="limitations"><a href="#limitations">Limitations</a></h2>
<p>Cookies are subject to size limits - we require session keys to be shorter than 4096 bytes. This
translates into a limit on the maximum size of the session state when using cookies as storage
backend.</p>
<p>The session cookie can always be inspected by end users via the developer tools exposed by their
browsers. We strongly recommend setting the policy to <a href="../enum.CookieContentSecurity.html#variant.Private"><code>CookieContentSecurity::Private</code></a> when
using cookies as storage backend.</p>
<p>There is no way to invalidate a session before its natural expiry when using cookies as the
storage backend.</p>

<p><code>CookieSession</code> creates sessions which are limited to storing
fewer than 4000 bytes of data (as the payload must fit into a single
cookie). An Internal Server Error is generated if the session contains more
than 4000 bytes.</p>
<p>A cookie may have a security policy of <em>signed</em> or <em>private</em>. Each has a
respective <code>CookieSession</code> constructor.</p>
<p>A <em>signed</em> cookie is stored on the client as plaintext alongside
a signature such that the cookie may be viewed but not modified by the
client.</p>
<p>A <em>private</em> cookie is stored on the client as encrypted text
such that it may neither be viewed nor modified by the client.</p>
<p>The constructors take a key as an argument.
This is the private key for cookie session - when this value is changed,
all session data is lost. The constructors will panic if the key is less
than 32 bytes in length.</p>
<p>The backend relies on <code>cookie</code> crate to create and read cookies.
By default all cookies are percent encoded, but certain symbols may
cause troubles when reading cookie, if they are not properly percent encoded.</p>

<p>You should not regret adding <code>actix-session</code> to your dependencies and going to production using
the default configuration. That is why, when in doubt, we opt to use the most secure option for
each configuration parameter.</p>
<p>We expose knobs to change the default to suit your needs—i.e., if you know what you are doing,
we will not stop you. But being a subject-matter expert should not be a requirement to deploy
reasonably secure implementation of sessions.</p>
