  I guess i wasn't clear - it doesnt work the way you expect.

  If you put in
  acl dstdomain my1.com my2.com

  Those domains are then allowed - but if someone hits the ip - squid
cleverly reverses the IP to a domain - if the reversed domain is allowed
by the rule then it is allowed.The same thing for dstdom_regex. Hence
the original question.
