Note: For a better experience I would recomment you to have Apache listen on port 80 as well. Just bind them to different IPs. This way you do not risk that port 81 to leak out to the end-user...

Squid doesn't really care where the DNS is pointing.. unless you have something relying on it such as the dst acl... the dst acl looks at the URL, not where the request is forwarded.. > since we have hundreds of domains.

Only if you set "httpd_accel_single_host on". With this off all the httpd_accel_* directives does is to reconstruct the hostname and port part of the URL from the request.. Regards Henrik
