Thanks Amos, what will change if the cache peer is talking ICP or HTCP protocol? Can I use one of this protocols to say if the answer is HIT or MISS, so the main squid who is in intercept mode to the customers, will mark the traffic? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/cache-peer-communication-about-HIT-MISS-between-squid-and-and-non-squid-peer-tp4600931p4602656.html Sent from the Squid - Users mailing list archive at Nabble.com.
