George,

There is a session_end event on the server side, but I suppose what you want is to detect it on client side.

To do that, you must set a timer on javascript, to end for example one minute before the session timeout and popup an alert. The alert gives the user the choice to extend the session. If the user says yes, then you make a post of the form (or an ajax call or anything that generates a request on the server side and so extends the session).
