Hi Amos, Thanks for your reply. Let's say I have the following cache_peer lines in (B), and the address for (C) is "forward-proxy.example.com:3128".
cache_peer origin-x.example.com parent 443 0 no-query originserver ssl cache_peer origin-y.example.com parent 443 0 no-query originserver ssl cache_peer origin-z.example.com parent 443 0 no-query originserver ssl What would be the syntax to configure (B) to use " forward-proxy.example.com:3128" (C) as the forward proxy to the origin servers (D) ?
