The latter. :-) The regular expression "x*" means "zero or more times the
letter x", so your pattern matches "", "",
"http://www.sexx", "http://www.sexxx", and so on. Just omit the asterisk
and you should be fine. (Btw, the dot is the wildcard character, so it
would also match, for example, "http://www+sex" or "http://wwwisex", but
these cases should be rare.)
