short answer: you can't catch all possible ways of users leaving your site. the closes thing you can do is update the tempDB each time the users requests a page (for instance updating a 'datetime_lastrequest' timestamp column). and then have a cron job running every X minutes that deletes all records where the datetime_lastrequest < (Now - X minutes)
