You might need to use several regexps to extract any valid format, then
see if you have anything left.
AFAIK, valid chars would be:
<cfset V = "[A-Za-z0_-]" />
so you check for 1-n V period 1-n V period 1-n V
that takes char of the domain address
from now on you also can have ~/&?%#
If you are doing this client-side, with _javascript_, be aware that
regexps work differently than with CF and with different versions of
_javascript_
If server-side, it is much better to do the cfhttp request, if you can.
