For those of you who don't know, Microsoft has a neat tool/utility out there called URLScan. It's primary job is to block traffic on a server that you don't want trafficing. :) We've recently released the 3.0 beta version, which adds some new features. Prior to my life at MS, a team I worked on used URLScan to block WebDAV traffic on our SPS2003 servers. I was talking to an old colleague yesterday and he expressed the need to block certain URLs on certain machines in his environment. The way they have things set up, they currently don't have any devices that can do this for them. By chance, today I found the new version of URLScan and found it added a new feature to do this.
UrlScan v3.0 Beta maintains feature and functionality parity with its predecessor (UrlScan v2.5). The configuration format is the same, but includes a few additional sections that can be used for the new features. If you are currently using UrlScan v2.5, you can use the same urlscan.ini configuration file with UrlScan v3.0.
Please check the Microsoft TechNet article here to get details about features for UrlScan v2.5. Here is a quick summary of the features in UrlScan v2.5.
