A site I go to creates a new random subdomain every so often... so this somehow
is making httrack work right.

The site starts out as:

<http://weo390fj.site.com/>

And httrack mirrors a chunk of the site, but then the site turns the subdomain
to a new random string. Say:

<http://6236rtew2.site.com/>

If I resume the site httrack stars downloading all over again...
