You cannot tell when the browser closes, there are many hacks, but none are
foolproof.
If you maintain a session object (your own, with state info) and if they
need to identify themselves somehow, you can restart an old session, or
invalidate it.
If you are tracking anonymous users, you are out of luck. You could try and
set a long lived cookie, but they might have cookies off, which is a default
for AOL users.
