    What about if a WebDAV application which depends on the use of that
    method ?
    If is not needed for example in a Exchange 2000 Outlook Web Access?

    I love UrlScan, don't misinterpret me... But in some case one may not be
    able to block the PROPFIND verb...
    
    So basically: 
    IF I DON'T USE IT, I have it disabled, the exploit won't work BUT I log
    it.
    IF I USE IT, the exploit will succeed, and no logging will be made.
    
    Am I wrong?
