could you explain this better?
Step 1: Clients are hitting successfully VIP.37
Step 2: VIP.37 requires to communicate with VIP.38
Step 3: VIP.38 requires communication with VIP.36 to fetch some files.
how is that communication exactly happening? or how do you believe it should be happening?
is vip.37 going to a pool with nodes or ...? are there links on the website (is it a website? for vip.37 pointing to vip.38?
in the general the idea with the virtual ... is how it works, but it must make sense as in general just a virtual server doesn't communicate with another one. a pool member might, or another irule might do it.
