Hi, I'm going to deploy multiple squid servers in a ISP for HTTP traffic caching. I'm now considering using WCCP for load balancing and TPROXY for fully transparent interception. Here is the problem. As far as I know, Cisco WCCP module does not maintain connection status, it just redirect packets based on their IP addresses and ports. I'm just wondering if it's possible that one squid server(squid A, for example) sends a outbound request, but the router redirects the corresponding inbound response to another squid(squid B)? Then that's totally messed.
