Hi I have implemented acls for blocking the porn stuffs. Those acls are for example using url_regex option, and thus it means blocking is done matching the expressions. that is a very large file of key words. As a solution I created an acl just above the blocking acl and allowed it just above it. the acl is acl update dstdomain .windowsupdate.microsoft.com but still at the time of updating, when it try to download/install the selected update, it fails. I think while downloading iin its url there are some words which matches the blocked list of words and hence the downloading fails? Any solution?
