  <section class="description">
    
<p><a href="Cookie.html"><code>Rack::Session::Cookie</code></a> provides simple cookie based session management. By default, the session is a Ruby Hash stored as base64 encoded marshalled data set to :key (default: rack.session).  The object that encodes the session data is configurable and must respond to <code>encode</code> and <code>decode</code>. Both methods must take a string and return a string.</p>

<p>When the secret key is set, cookie data is checked for data integrity. The old secret key is also accepted and allows graceful secret rotation.</p>

<p>Example:</p>

<pre>use Rack::Session::Cookie, :key =&gt; &#39;rack.session&#39;,
                           :domain =&gt; &#39;foo.com&#39;,
                           :path =&gt; &#39;/&#39;,
                           :expire_after =&gt; 2592000,
                           :secret =&gt; &#39;change_me&#39;,
                           :old_secret =&gt; &#39;also_change_me&#39;

All parameters are optional.</pre>

<p>Example of a cookie with no encoding:</p>

<pre class="ruby"><span class="ruby-constant">Rack</span><span class="ruby-operator">::</span><span class="ruby-constant">Session</span><span class="ruby-operator">::</span><span class="ruby-constant">Cookie</span>.<span class="ruby-identifier">new</span>(<span class="ruby-identifier">application</span>, {

})
</pre>
