You could use a session listener and check its existence with a
filter... In other words:
// filter pseudocode
if( null != session.getAttribute( "UserMarker" ) ){
// pass the req and resp down the filter chain
}else{
// forward() to a "your session timed out" page
}
Is this what you're after?
Option #2: have each page meta-refresh to the "your session timed out"
page (set the refresh value 1 or 2 seconds beyond the session timeout).
This is more intrusive, though: people don't typically like it when
their browser starts moving around when they didn't explicitly ask.
