Hey!
We just started to use a Big-IP 9.x 6400 and are trying to get 4 People Soft web servers setup behind it. They are running WebLogic.

on our 8.3 system on the web profile page in the virtual addressing tab, we enabled the generate relative URL's option and specified the protocol, name, and port of our F5 virtual server.
