RE: [squid-users] How to deny unmatched/unspecified domains in squid 2.6 under reverse proxy mode?

By the way, I found a simple way to block access without using acl by one minor change to the code. In case someone needs that behavior. It is in the neighbors.c, function peerAllowedToUse. Initiate do_ping =1 instead of do_ping=0 would do it. Not sure the reason for returning that the peer is ok to use if the peer_domain ==NULL or access==NULL. Perhaps it is applicable for the forward proxy?

Khanh

It works. Very clever way of creating acl. It makes it more manageable.
I guess that there is no undocumented option in squid.conf to disable the use of default parents for domains that are not specified under the reverse proxy mode. It seems to be undesired behavior :-|

Can the squid cache be configured to return error page or acl denied page if a request is for a domain that is not configured in the squid cache server? If I use acl to achieve this, would i have to one allowed acl for each configured domain and then deny at the very end? It does not sound very effective since I would have a very long acl list. My cache server would have over 100 domains thus 100+ acl. Is there any better way without modifying the code itself?

http_access deny !KnownHosts

Where "file" would contain the allowed domains, one per line with an
optional leading dot to match all subdomains. Be sure that this
http_access deny is entered before any explicit allows in your squid.conf.
