What about timing out the session on the server?
Assuming that you're using a Java application container on the server,
you can add the following to web.xml:
<session-config>
<session-timeout>5</session-timeout>
</session-config>
This will cause the server to time out connections after five minutes
of inactivity. With this technique, it's actually possible to
intercept requests made after a time out in the onFailure() handler
and to take some kind of action (i.e., redirect to a login screen).
