Caching the BIG-IP GUI

Hi guys, here is an interesting one. I have about 100 BIG-IP's I want to access through a varnish cache. Seeing as the GUI is identical on all the F5's their are benefits from caching. Would any of you have any intimate knowledge of the F5 GUI and what its composed of. Just so I can nut out what settings may be useful to optimize the behavior of varnish.
