[Peter Sawczynec]

Couple of alternate solutions (viable but got pitfalls):

1) Tiny JavaScripted popup or popunder window polls the opener page for it's
existence. When opener page disappears, the popup window does location
change to PHP logout page, processes, and then closes itself. 

2) 1x1 transparent gif src points to PHP script page that polls for
"connectin_aborted" and fires logout script when true.

What about using <meta http-equiv="Refresh" content="60; http://yoururl"> in
the header of the page?

As i understand it, this would try to grab a new copy of the page every
minute (modify the 60 if you want a longer or shorter time).  By keeping
track of when the reloads cease, you'd know when the visitor closed the
browser (or lost network connectivity) even if she/he didn't hit the logout
button.

And surely it'll be no picnic to integrate something like this with your
already existing authentication code (so that it works seamlessly and
doesn't demand a new login on every automatic refresh once a minute).  And
if your pages are places where people can input data (via forms), it'd be a
real drag to have the page automatically reload (and lose the paragraph or
so of text that your visitor just entered in a form field(s)).
