title: Session expiry times?
body: <p>I've enabled sessions on my app:</p>
  
  <pre><code>// appengine-web.xml
  &lt;sessions-enabled&gt;true&lt;/sessions-enabled&gt;
  </code></pre>
  
  <p>they seem to work when I load different pages under my domain. If I close the browser however, looks like the session is terminated. Restarting the browser shows the last session is no longer available.</p>
  
  <p>That could be fine, just wondering if this is documented anywhere, so I can rely on this fact?</p>
  
  <p>I tried the following just to test if we can tweak it:</p>
  
  <pre><code>// in web.xml
  &lt;session-config&gt;
      &lt;session-timeout&gt;10&lt;/session-timeout&gt;
  &lt;/session-config&gt;
  </code></pre>
  
  <p>also</p>
  
  <pre><code>// in my servlet
  getThreadLocalRequest().getSession().setMaxInactiveInterval(60 * 5);
  </code></pre>
  
  <p>but same behavior, session data is no longer available after browser restart.</p>
  
  <p>I looked at the stats for my project and I see data being used for something like "_ah_SESSION" objects. Are those the sessions from above? If so, shouldn't they be cleaned since they're no longer valid? (Hopefully gae takes care of that automatically?)</p>
  
  <p>Thanks</p>
