Re: http://www.domainname.com./ (with the ending)

[Mark Burnett <mb () xato net>]

Basically what you are doing is providing a domain name that it does not recognize. It therefore either tries the 
default web site (either Under Construction or the actual web site) if one is configured or returns a 404 error if 
there is no web site configured. If the site has URLScan installed, you will see the 400 error message. You would get 
the same effect by browsing directly to the IP address of the web site and not providing a host header.
