Configuring load balancing with SSL termination and stickiness for a couple of citrix xenapp servers. I'm doing a source-NAT as the ACE resides in the DMZ and these particular servers reside on the inside arm of the firewall. The ACE is in bridged mode to load balance web servers that reside in the DMZ. Everything seems to work just fine, but the cookie stickiness does not seem to be working.
I also just found a bug that could be relevant here. The issue can happen any time a user changes the serverfarm within a sticky group. It can cause sticky to stop working. It was fixed in A2(1.5) on the module and A3(2.3) on the 4710.
If upgrading is a possibility for you, it wouldn't be a bad idea to jump to A3(2.4).
