"The URL you gave me returned a redirect to <http://localhost/>"

Another case of this annoyingly strange redirection reported throug 
bugzilla today:
http://www.w3.org/Bugs/Public/show_bug.cgi?id=1069

For all the three reported cases, two were using the same ISP. The 
third (Ron) apparently managed to get the issue fixed by contacting his 
WebHost's tech support.

All three cases happen with instances of:
Server: Apache/1.3.31 (Unix) mod_log_bytes/0.3 FrontPage/5.0.2.2635 
PHP/4.3.10 mod_ssl/2.8.19 OpenSSL/0.9.7d

More details on the bug report comments section, but I would not be 
surprised if some web hosting bundle came with either a buggy version 
of apache with FP extensions, of a silly config option.

This will have to be investigated further, in the meantime, let's point 
new reports of this issue to either this post or the bugzilla entry.
