Re: [squid-users] Alteon + squid

You probably would get a more cost efficient setup by using a 1.5
layer setup, having the load balancer distribute the load on both
your boxes and using internal request routing to reforward requests
to the correct cache box if arriving at the other..

squid.conf for your .com box would then look something like

cache_peer the.notdotcom.box parent 3128 0 no-query connect-timeout=2
proxy-only

acl COM dstdomain .com

cache_peer_access the.notdotcom.box deny COM

prefer_direct off
