I don't know if Tomcat itself offers options for load balancing...but I wouldn't be surprised if it does....what I was discussing was the possibility of Tomcat doing session sharing between the servers which would potentially prevent the situation where all users on the server that went down loosing their session.

If you configure multiple mid-tier servers behind a load balancer, if one of them goes down then the load balancer would re-point them....which would force them to log back in because their session is invalid on the other server....but I did look into Tomcat clustering that did session sharing, but didn't get far enough down that road to actually test anything. ________________________________ From: Action Request System discussion list(ARSList) [mailto:[EMAIL PROTECTED] On Behalf Of Kaiser Norm E CIV USAF 96 CS/SCCE Sent: Tuesday, August 19, 2008 1:51 PM To: [email protected] Subject: Midtier Clustering ** Hi everyone: Is it possible to create a high availability Midtier cluster? That is, a cluster of Midtier servers that behave as a virtual single server so that if one server fails the other picks up the load without the end users noticing?
