i think you're waging a gamble that is much too risky by relying on
javascript to kill sessions on the server.  that would be what is considered
venturing into using javascript for things that are mission critical.
instead, clear the sessions after a given time of inactivity and develop a
client-side method with which to lengthen that time, if necessary.
lengthening sessions is as easy as swapping an image with the image path
being to a serverside template that returns a content type for a new image.
the server sees activity for that session and nothing changes on the page
for the user.  user leaves the site or closes their browser and their
session eventually times out.  everyone is happy.

just my 2¢,
