RE: Double Slashes

["Andres Molinetti" <andymolinetti () hotmail com>]

This IIS has no URLScan running. That's the odd thing. Therefore I think it 
may have been a patch or something.

What I need is a way that the server doesn't strip my slashes and let me 
send an url like this "www.example.com/dir//page.asp".

Any ideas?
