Which version of squid are you using ? squid -v Also interesting to see the ./configure options. Do you really need 1/2 parent proxies ? Or do you simply want to split up the traffic to the two interfaces ? In case you need parent(s), then I would use 2. (Although it should also be possible to do everything within just one parent) Simply to make the setup "safer". Because you will have to fiddle around with https-part for quite some time, I guess, so not to touch the other branch. :-) Splitting up to two parents can be done using something like acl google url_regex -i ^https?://.*?google\.com/ cache_peer xxx.xxx.xxx.xxxx parent 3128 0 no-query no-digest no-netdb-exchange name=default_parent cache_peer yyy.yyy.yyy.yyy parent 3128 0 no-query no-digest no-netdb-exchange name=google_parent cache_peer_access google_parent allow google cache_peer_access default_parent allow !google #Not shure, if next ones are necessary. However, sequence of ACL checking is sometimes a bit strange #cache_peer_access default_parent deny google #cache_peer_access google_parent deny !google -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/peer-cache-question-tp4659419p4659453.html Sent from the Squid - Users mailing list archive at Nabble.com.
