If you want to clear items from a cache when a user logs out, then you may
want to use Sessions instead of the Cache object.

Regardless, if you want something to happen when a user leaves a site, you
can stick code in the session OnEnd event. It's harder to make something
happen when they close their browser, though -- you'd have to trap the
page's onunload event using javascript, which is a pita.
