All, I put line "cache_peer my.peer.addr sibling 8080 3130" in squid.conf. Then I found message below: 1109354349.317 190 192.168.1.3 TCP_MISS/304 243 GET http://www.openoffice.org/branding/scripts/tigris.js - SIBLING_HIT/202.136.64.52 application/x-javascript So, I assume that my machine successfully joining cache hierarchy. Please correct me. Thx & Rgds, Awie
