For the option A (with dns server). If the dns server's IP is 192.168.10.10 dns_nameservers 192.168.10.10 #is this the way to configure it? For the option B (squid will be in charge of the logics): If the web server's IP's are wsIP1, wsIP2 and wsIP3 cache_peer wsIP1 parent 80 0 no-query originserver name=S1 round_robin cache_peer wsIP2 parent 80 0 no-query originserver name=S2 round_robin cache_peer wsIP3 parent 80 0 no-query originserver name=S3 round_robin acl S1_domains dstdomain site.domain acl S2_domains dstdomain site.domain acl S3_domains dstdomain site.domain cache_peer_access allow S1 S1_domains cache_peer_access allow S2 S2_domains cache_peer_access allow S3 S3_domains would this e the way to set it?
