I posted this to bugtraq, but I'm not sure if it 
will be posted, so I will post here too...

I recently viewed a web page on a server running 
IIS 4.0 and accidently appended a \
after the url. This to my suprise caused the page 
to download. This occured under
Netscape 4.6 (IE5 appears to ignore the \). I was 
wondering if anyone else could
confirm this behavior. It is not my server so I 
cannot do extensive testing on it, so I'm
bringing it to the community. The file that 
downloaded was a .html file, however I am
curious if appending a \ has the possibility of 
downloading .asp's or .cgi's. If that was
true it would be a definite security hole. Email 
me hypoclear () jungle net or the list with
any findings.
