We developed a asp.net web application which uses an ashx handler to do partial file Uploads. A user can select files via a silverlight control and the control starts a Post HttpWebRequest to the ashx handler and transmits the file in smaller chunks (via HttpWebRequest.BeginGetRequestStream) so that the silverlight control can Display a Progress bar.

Now we want to expand on this solution to support Uploads to WebDAV Folders.
So the main question is: Can this "chunk-wise" upload be done via WebDAV at all?
