Killing User Sessions upon closing window

[Guest]

How can we kill the user session people if people just go in and close the window by hitting x on the top of the browser? Any feedback and help would be greatly appreciated.

Technically, you can't kill a user's session upon them closing the window.

What you _can_ do is use J2EE session tracking, or a transient cookie that gets deleted when the browser quits. That still doesn't kill the session when they close the window. The session remains active until the timeout time has elapsed.
