implementation which clears the directory when it receives a
sessiondestroy callback. This will do your cleanup automatically and
does not rely on client-side scripting which sometimes doesn't work:
(Examples: computer shuts off/unplugged, User kills the app, non
standard browsers, etc).

Unfortunately the only way to resolve this will be to employ a
_javascript_ tactic which will prevent the user from being able to use
their refresh or back buttons while they're using the application.
Open the application in a fameset or an iframe. Then add an onunload()
and onbeforeunload() event (for IE because IE handles it in a
non-standard way) to the top window which launches the logout page in
a separate frame or iframe. When the user closes their browser
(without hitting the logout button - or if they refresh or go back),
it will automatically load the logout page that frame or iframe prior
to closing the browser. Popup killers won't affect it because it's not
a popup, although you do need to be sure that users have _javascript_
enabled before they log-in, which can be done by dynamically
populating the login form. In other words, when they go to log in, the
page presents a "we're sorry, you must have _javascript_ enabled"
message. Then a bit of _javascript_ replaces that message with the
log-in form. If you need help with any of this I've done it before
myself, so just let me know.
