Rule #1 - you cannot close a browser window by issuing an instruction from
the server.
Rule #2 - a user does not have to use any logout mechanism that you provide,
he can simply close the browser window.
This means that the user may have finished with your application but your
application still records him as "active".
If you write your session data to a database file you can store the user_id
in each record. Then during the garbage collection on the session table you
can extract the user_id an update that record to "logged_in=FALSE" or
whatever.
