What version of IIS, CF, and URLScan? Also, something I believe I forgot to mention earlier... there's an option to hide what type of webserver you're running. Do you have that turned on or off? I don't recall for sure but I seem to remember that if you turned the "hide" feature on you got problems.
Another problem with URLScan what that it really slows down pages that have a lot of images. For example, a product catalog application that had 20-30 thumbnails per page ran extremely slow. We determined the cause to be due to the fact that URLScan scans (obviously) every request to the server. A page request with 20 image thumbnails on it results in URLScan scanning 21 URLs. The original URL, and the URLs for the 20 images. Removing URLScan sped up performance considerably. Obviously this "slowdown" would only affect you if you were serving up pages with a lot of <IMG> tags such as a product catalog. -Novak ----- Original Message ----- From: "Robert Everland" <[EMAIL PROTECTED]> To: "CF-Talk" <[EMAIL PROTECTED]> Sent: Friday, October 11, 2002 11:01 AM Subject: RE: Microsoft UrlScan and CF > I use urlscan and it works fine. > > Robert Everland III > Web Developer Extraordinaire > Dixon Ticonderoga Company > http://www.dixonusa.com > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > Sent: Friday, October 11, 2002 2:00 PM > To: CF-Talk > Subject: Re: Microsoft UrlScan and CF > > > Dave, > > It was several months ago that I delt with this exact same situation.
