Re: [squid-users] Alteon + squid

Have verified that cache_peer_domain, cache_peer_access and
neighbor_type_domain can be used to only forward !.com to parent. Actually
we could have use hierarchy_stoplist .com too, but, this will also include
.com.x traffic.

I notice that putting proxy-only in cache_peer (not to cache !.com
objects) will somehow cause the .com objects not to be cached also. Did i
miss out something in the config?

cache_peer notdotcom.box parent 8080 3130 proxy-only no-query no-digest
hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY
acl COM url_regex ^http://.*\.com(/|\b)
cache_peer_access notdotcom.box deny COM
