That is almost but deceptively not quite the same as "allow all".

No, sorry. It is not.

The correct config is to use:

 http_access allow foo

Where "foo" is the same ACLs you use on cache_peer_access to determine
which traffic goes to the peers.

That way Squid is able to block random other domains that virus scans
etc try to use to detect open proxies.
