Hello, I'm trying to run HTCP protocol over squid 2.7. Unfortunately, it isn't working. We are monitoring HD cache(cache_dir) size thorugh du command, and it isn't increasing. We tested the same envinroment with ICP, and cache size is increasing. Below, configuration of one of four cluster nodes. The others are similar, changing just IP address of siblings. cache_peer 192.168.15.253 sibling 3128 4827 no-digest proxy-only htcp cache_peer 192.168.15.252 sibling 3128 4827 no-digest proxy-only htcp cache_peer 192.168.15.251 sibling 3128 4827 no-digest proxy-only htcp htcp_port 4827 acl cloud src 192.168.15.0/24 htcp_access allow cloud htcp_access deny all log_icp_queries off icp_port 0 digest_generation off # Disables cache digest access.log also do not report anything. (We read on Wessels's book that HTCP isn't logged. Is it true on 2.7 version?). Some clue? Thanks in advance, Igor.
