I've been seeing this message on the list for a few days, and haven't responded because I didn't have any suggestions for you. Since nobody has answered, I'll go ahead and give you my thoughts.

Or to have the PollingServlet use a different, perhaps > transient, session? This is not really possible, but there are other possibilities. Consider this one: You write a filter that updates an in-session timestamp of the last time the session was used "meaningfully": that is, by some truly useful thing, instead of one of these polling requests. Map this filter to all URLs /except/ those that do this kind of polling. Now, in your polling servlet, you check this value and expire the session if the "last meaningful use" of the session exceeds the timeout configured for sessions (which is easy to check). If it does, expire the session and return an error to the polling caller. What happens to your GWT-based polling process if it gets an error? Will it keep polling forever, getting errors? Or, will it go into an error state and stop bothering the server? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktXY80ACgkQ9CaO5/Lv0PAWGQCfR0ru/bPn6mfnDyesGn3rr9Vp uuIAn2rePjy5HU9/5GUWK9N5bQ7GJ8Xv =TzbK -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
