I am trying to map the drive through windows explorer to webdav server. The URL I am trying to map to is : "https://sandbox.libraries.ge.com/desktop/folder/2206731816068". I am tracking request/response through Fiddler HTTP debugger. When I map the drive the first request after CONNECT I see is "OPTIONS /desktop/folder/2206731816068 HTTP/1.1" to which Apache Server's response is "HTTP/1.1 401 Unauthorized". Then it again calls CONNECT and then fires "OPTIONS /desktop/folder HTTP/1.1" to which Apache Server's response is "HTTP/1.1 401 Unauthorized". Then it again calls CONNECT and then fires "OPTIONS /desktop HTTP/1.1" to which Apache Server's response is "HTTP/1.1 401 Unauthorized". Then it again calls CONNECT and then fires " OPTIONS / HTTP/1.1" to which Apache respond with "HTTP/1.1 302 Found". Did you notice every time it calls OPTION it remove one folder from the request. First it was "/desktop/folder/2206731816068" and the last one was "/". "/" is SSO procted so it ask for the login and password which we DON'T want. I need "/desktop/folder/2206731816068" to respond with HTTP/1.1 OK. What should I setup on APACHE web server so that it allowsw OPTION method to ""/desktop/folder/2206731816068" or to ""/desktop/folder/". Early reply appreciated. Thank You.
