Re: Session Invalidation

i am unsure if there is a way to do this in pure java, but here's a
javascript solution:

place a javascript function in a universal server-side-include (if you
have a header.jsp which standardizes the header for your page, this is a
perfect place)...then, trigger your function to be called with an
"onUnload=" listener in your page's <body> tag...have your function post
to servlet or jsp which performs your logoff routines...

this is the same trick that porn sites have used for years to lock you
into their site, and though it's not a perfect solution in that
javascript can be turned off, it's likely that most users will have
javascript enabled and will not object as the entire process should be
invisible to them

hope this helps!
