dtsdom* will only do a lookup if the URL content is a raw-IP that fails
to match the pattern. "regular URLs" already have a domain named so no
lookup is needed.
Also, if an asynchronous lookup is required by an ACL when testing in
the non-blocking (fast) access check the ACL is considered a non-match.
The inverted (!) result is also a non-match which can confuse.
