You can't, actually, because there is no way of knowing that the user has
actually left your page.
Either provide a link for them to log out (so the sessions for those who
decently log out are ended right away) or set your timeout period rather
short (or both)
You could also try some client side JavaScript that is run in the OnUnLoad
event. In that event, call an ASP page with the Session.Abandon method in
it. This method is far from guaranteed to function. It will not always
fire, it can be prevented from running, it can be a pain for the client and
older browsers might not support it.

Having a 'Logoff' link or button may seem like a great idea so that you can
clean up and data setup during the duration of the session - but IMHO users
just 1) close the browser or b) navigate away from your page. In my
application is critical to know if the session went away, so we created a
little ActiveX control that sits in the main nav bar frame and sends a
heartbeat via TCP once every minute. If no heartbeats are received within 3
minutes, the sentinel program on the server tells all interested programs
that a particular user session has been terminated. It's far from
fool-proof, but it gets the job done

This looks good may is the right way, I agree that users normally don't use
the logout button or something like that they simple close the windows. I
have been using the Unload event but as another person says it doesn't work
at all the times and is far from perfect.
This ideia of using something to get pulse from aplication is good could you
send me some example how to do it? I'm new to activex but I have some
experience at visual basic. I really need that any help will be apreciated.
Thanks

Only problem with Active X Controls is that they only work on Internet
