how do I configure squid to make it always go through parent proxy to some domain? In my situation, some websites are blocked by firewall and I made an openvpn from my local proxy to parent proxy and I'd like to force my local squid to always go through the parent proxy via openvpn when visiting those domains. Now the openvpn was built well but I have no idea making squid go through parent proxy only for those defined domains and always direct for other domains. idea?
