I did an AJAX version of this a couple of months ago.
The slight gotcha is that the AJAX request prolongs the life of the
session (you can't, it seems, override the cookie for AJAX requests) so
the interval has to be slightly longer than the expiry time for the session.

session timeout. When the session times out, the user gets no notification
of this event. Is there any way to show the user that they have logged out?
