My initial thought was the cookie's session id would remain constant for the life of the cookie (ie session timeout). That's not what I have seen though. A unique session id is assigned by 4D when it creates a session process. I tried reading the cookie of new processes before doing anything else but this always comes back empty until it gets set by 4D with the current session id. This makes sense - but it doesn't give me a way to recognize the unexpired session in the context of this particular process. I suppose I'm questioning if setting the 'Web inactive session timeout' even matters so long as it's at least as long as the process timeout. Is there any difference between the 'session' and the process that session is running in? If there is I'm missing it. If there's not then the solution is like Tim's tech note and you outline, track it by something else like user id and basically ignore session timeout. -- Kirk Brooks San Francisco, CA ======================= ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
