<h2 id="limitations"><a href="#limitations">Limitations</a></h2>
|
||
<p>Cookies are subject to size limits so 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="../config/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>
