I see. So it's not that you need a hook into Trinidad's ppr mechanism
so much as you want to generate a ppr request yourself using Trinidad's
apis. Does that about sum it up?

The client side code would involve using a JavaScript timer that is
created using the standard setTimeout(expression, timeout) call. This
timeout period would be slightly shorter than the timeout period that
is set on the server. The expression argument would call a function to
display the "Session is about to expire dialog". Once the dialog is
displayed, another timer is created that will clear the dialog and
cause an AJAX call that would invoke a servlet to expire the session
on the server if the user doesn't respond within a short amount of
time. If the user clicks the "Continue" dialog button, an AJAX call is
made to a servlet that will refresh the session.
This is how many online banking applications handle session timeouts.

I guess I'm confused as to how the code on the client side would know
the session is about to expire without doing a ppr?
