Similar to 'cache_peer_domain' but provides more flexibility by
	using ACL elements.

	Usage:
		cache_peer_access cache-host allow|deny [!]aclname ...

	The syntax is identical to 'http_access' and the other lists of
	ACL elements.  See the comments for 'http_access' below, or
	the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
