I'm sure this won't be an issue for everyone, but seems strange to me that URLs
that start with <http://file://> will actually do the return the file instead
of an invalid URL message or DNS error. We thought we were blocking everything
but "http" and "https" requests, but this type of URL got around our
whitelist.

httrack --get <http://file:///etc/passwd>

:-(

Just a good thing for others to know who are using httrack in their scripts.
