Bin, Thanks for your reply. We're working on a Squid configuration for ISP customers and it would be really interesting to hear about any potential problems with this configuration. >> How far have you gone to make Squid truly transparent eg >> * suppressing the Squid headers, error messages etc. >> * Is there any way to configure Squid / Cisco to give SYN_ACK, >> "connection refused" and ICMP "host unreachable" responses rather than >> Squid error messages? >> * Can you force Squid to make its request from the same source port >> as the client. > > You mean totally transparent and the clients don't even know the > existence of squid by any means? It seems a little bit difficult... Yeah, I agree. It's going to be impossible to totally hide Squid, but we're going to do as much as we can. >> * If someone uses port 80 for a protocol other than http, can Squid >> reject the redirected traffic in such a way that it is passed through >> directly instead? > > WCCPv2 can support this feature by Packet Return Method.
