Hi All I had linked squid servers into a cache hierarchy. One Child and two Parent. below is the Child config cache_peer p1.example.com parent 3128 3130 weighted-round-robin cache_peer p2.example.com parent 3128 3130 weighted-round-robin Here is my question, if let say, the p1.example.com was down, is it all the traffic will go thru the p2.example.com ? if not, any solution to avoid the service downtime ?
