Hi All, Recently I am working on building a squid caching hierarchy which would accelerate one of my websites. I would put up about 6 squid servers. As far as I know, there are at lease 2 inter-cache communicating protocols, namely ICP and HTCP, also there are cache digests and CARP. According to my requirements above (6 squid servers), which inter-cache communicating protocol is the better for me? Can anybody give me some advice or suggestions, with performance, accuracy and speed analysis? Thank you in advance. Yours, Xu Feng Shanghai,China
