Session Events

[Ricardo Cortes]

The following is from the servlet 2.3 specification. Could someone please inform me just how one can tell whether a session was invalided because the session timed out or the application called invalidate?
"Listener classes provide the developer with a way of tracking sessions within a web application. It is often useful in tracking sessions to know whether a session became invalid because the container time out the session, or because a web component within the application called the invalidate method. The distinction may be determined using listeners and the HTTPSession API methods".

[Peter den Haan]

The HttpSessionEvent gives you the HttpSession that is being destroyed. You can then compare (System.currentTimeMillis() - session.getLastAccessTime())/1000 with session.getMaxInactiveInterval() and determine whether the session has expired. If not, it must have been invalidated.
