While running performance testing I've noticed that all the requests from any given IP address seem to all be going to the one cluster member.
I've got about 7 concurrent users plugging away, and one server's got log activity while the other is sitting idle.
Needless to say this is going to mess up my testing results unless I can find a farm of computers to be pretend clients. (It's an option)
Is the web server assigning requests to servers based on the client ip to try and maintain sessions or something similar? Is there some configuration item I'm missing? Or am I just getting extremely bad RNG luck?
