Hi Jens,
That's my local workstation IP address, where I'm running Tomcat. Since I can use the GemFire cache normally (simple get/set operations, etc.) without problems, and it's only the HTTP session management module that seems to cause trouble, I assume I've just got something mis-configured somewhere. If GemFire is trying to create a connection to my local machine, any idea what that could mean? Maybe it's trying to use p2p instead of client/server, and/or I haven't correctly supplied the server and port info, something like that?
Thanks so much for all your help,
-Will
