Hi all i am brainstorming to setup a 2 tiers proxy farm. I have a layer 4 switch which forwarding http traffic. I would setup 2 tiers : 1st tier: receiving traffic from layer 4 switch and forward to 2rd tier according to the destination/host IP(in this tier, nothing would be cached.) 2rd tier: receiving the traffic from 1st tier. Return the cached object if available or download the object from originated web server. (cache in here) Since i have layer 4 switch only, I would setup a tier to forward the traffic by destination host for increasing the hit rate. Do anyone have same idea? Thanks Best Regards, RR
