Dears, does anyone have a section of a squid configuration file that shows a basic hierarchical configuration? My doubt is related to parent-child relationship. My environment has 4 nodes, one parent (frontend - 192.168.15.254) and three children: node01: 192.168.15.253 node02: 192.168.15.252 node03: 192.168.15.251 Parent and siblings relationship were implemented like that (on node01, for example): cache_peer 192.168.15.254 parent 3128 3130 no-digest default proxy-only cache_peer 192.168.15.252 sibling 3128 3130 no-digest proxy-only cache_peer 192.168.15.251 sibling 3128 3130 no-digest proxy-only Similar configuration will be found on other children nodes. Nevertheless, how cache_peer directive configuration should be performed on parent node, so that nodes 01, 02, and 03 are seen like children? Should it be implemented with ACLs? Thanks in advance, Erico Augusto
