Switching from dstdomain to url_regex will likely be much less
efficient. dstdomain searching is probably O(log N), while url_regex
searching is O(N).

There are some redirectors (like Squirm, Jersed, and squidGuard) that claim
to be very fast and efficient. You might be able to do regex searching with
them faster than with Squid's internal implementation. A nice thing about
redirectors, too, is that you can test them separately before you configure
Squid to use them.
