Re: [squid-users] Pre-Proxy with Squid

I would recommend trying

cache_peer ip.of.proxy.server parent port_of_proxy 0 no-query
never_direct allow all

And if you two or more parents for different connections, define both
and use cache_peer_access (or cache_peer_domain) to define what
should go where.
