This is quite strange, I think I'm misunderstanding something.
I'm using squid as a reverse proxy.
Clients (internet people surfing on my website) should connect to squid
boxes to retrieve static content. Squid send the right file or connect
to cache_peer to retrieve file before the resend process.
How can someone could tell to squid to retrieve something on a server
not defined to a cache_peer ?
