When certain MIME types are detected by IE, IE will open the URL directly in the registered handler.
For example, if I enter this address in the IE address bar: http://www.somesite.com/word.docx, IE will launch Word, and when I look at the properties, Word will show that the file is from location http://www.somesite.com/word.docx. This means if the server supports WebDAV, the document can be edited directly from that location.
But when I do a Navigate with the WebBrowser control with the same URL, the WebBrowser control downloads the file to the local cache, THEN runs Word against the locally cached file instead of using hte URL.
Is there a way to get the WebBrowser control to launch Word with the URL and not the downloaded file? Or is this type of handling actually a feature of IE and not built into the control (in which case I would have to implement it myself by reading MIME types from the registry, looking at the web request, etc.)?
I have enabled FEATURE_MIME_HANDLING for the process, but that doesn't appear to affect the behavior.
