Should be quite easy. Way to go is to define a parent proxy in your private squid as default. And then using always_direct/never_direct (squid.conf keywords) for the exceptions. So, something like .... cache_peer 192.168.0.1 parent 6139 0 no-query no-digest no-netdb-exchange #To define co's proxy ... acl to_locanet dst 192.168.0.0/8 .... always_direct allow to_localnet never_direct allow all in your squid.conf -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Using-squid-to-bridge-proxies-tp4664573p4664579.html Sent from the Squid - Users mailing list archive at Nabble.com.
