I think the JavaScript is the way I will go as the hidden frame refreshing
creates a click in IE I believe.
Is there a way to do this built into the later Tapestrys?

Hi James, et al.
Opps - I answered the wrong question. As Thiago writes, you would indeed
need to use javascript to periodically fetch something from the server,
and in particular something that the servlet engine processes, so that it
knows to update the last accessed timestamp on its internal HttpSession
object mapping to that browser. A simple AJAX call would do well here -
just ping a dummy T3 page or something. Alternatively, use a Frame
(perhaps a hidden size 0 Frame) with a body reload - which will work even
if the browser doesn't support javascript.
You can then leave the default servlet timeout for sessions, so that if
the browser is closed, the session object will eventually timeout and be
GCed.
Cheers
Richard

No way unless you use some Javascript hack that keeps requesting
something
to the server. You must remember the nature of HTTP. The browser connects
to
the server, receives the answer and the connection is closed. There is
nothing like a browser closing event notification sent to the server.
