<p><a href="Pool.html">Rack::Session::Pool</a> provides simple cookie based
session management. <a href="../Session.html">Session</a> data is stored in
a hash held by @pool. In the context of a multithreaded environment,
sessions being committed to the pool is done in a merging manner.</p>
<p>The :drop option is available in rack.session.options if you wish to
explicitly remove the session from the session cache.</p>
<p>Example:</p>
<pre>myapp = MyRackApp.new
sessioned = Rack::Session::Pool.new(myapp,
:domain => 'foo.com',
:expire_after => 2592000
)
Rack::Handler::WEBrick.run sessioned</pre>
