Hmm, I just read those two thread and I didn't see a final solution. Is getJvmRoute() unique across tomcat instances running on 5 web servers all serving the same app using a JDBC session manager. I know session id is unique within a webapp but what about over a cluster of webapps that don't use sticky sessions? All that blather about it being a statistical improbability that a session id will be duped is crap. It has to be IMPOSSIBLE across a non-sticky cluster for a dupe session id to be generated. --Angus
