OR IPv4-mapped address format,
OR that port can be included,
OR the fact that raw-IP can be used on any request..
acl ips
^(([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)|(\[([0-9a-f]+)?:([0-9a-f:]+)?:([0-9a-f]+|[0-9\.]+)?\]))(:[0-9])?$
http_access deny CONNECT ips
deny_info TCP_RESET ips
Getting complicated...
So xxiao8, why does one want to censor these requests anyway?

Thanks for all the replies. The reason is to enforce dns-based filtering
so you can't type in IP to bypass it easily.
