Excellent post from Robert McMurray :
I've mentioned in previous blog posts that I use the Windows WebDAV Redirector a lot. (And believe me, I use it a lot.) Having said that, there are a lot of registry settings that control how the Windows WebDAV Redirector operates, and I tend to tweak those settings fairly often.
I documented all of those registry settings in my Using the WebDAV Redirector walkthrough, but unfortunately there isn't a built-in interface for managing the settings. With that in mind, I decided to write my own user interface.
