Hi Everyone, Nowadays I am planning building a load-balanced squid + web nodes cluster. The detailed information: Operating System: Linux 2.6.9 Squid-2.6-Stable-15 Here we have two options: squidA + Apache1 Lvs + squidB + Apache2 (Lvs = linux virtual server) SquidA forms sibling relationship with SquidB using ICP. Apache1 is parent (original server) to SquidA. Apache2 is parent (original server) to SquidB. The other is Squid-parentA + apahce1 Squid-child + Squid-parentB + apahce2 Squild-child round robins Squid-parentA and Squid-parentB. Anybody has any suggestions on the two options? Which is better of the two implementations? Xu Feng Yuanjie Networks,Shanghai,China MSN: xufengnju@xxxxxxx
