 A target may, however, contain a wildcard in one portion of the domain
 (like *.google.com or google.*, but *.google.* would not work). A wildcard
 on the left will match arbitrarily deep subdomains (for instance,
 *.facebook.com will match s-static.ak.facebook.com).1

 Exception: currently this is not true for a target host that is less than
 three levels deep. <target host="*.com"> would match thing.com but not
 very.thing.com. We would consider changing that if anybody needs to use
 it. <target host="*"> means a ruleset should be tested for every single
 URL.

 Sure, all fine. But put a said host='*.2ld.tld' in xmlconfig, and browse a
 4ld.3ld.2ld.tld, and you will not be rewritten. So it's broken, or
 counter-documented.

 I would fix it by sticking to the (pcre.org / www.regular-
 expressions.info/pcre.html) that the rules overall seem to conform to,
 rather than making the separate documented hack...
 host='^.*\.2ld\.tld$' is not so bad.... assuming I got this report right,
 that is.

 If not, what regex are the rules written in?
