I have a public SharePoint site. It is configured and working correctly except for mobile devices. The site contains some folders that I think were created by the authors in SPD. An example I will use is the 'images' folder.
When a client browser requests the home page, anonymously, everything works fine. The page is loaded including all the resources files, css, js images etc. This works for all user agent settings I have tried.
The problem I am having is that when the HTTP request is from a mobile device, so the user agent string indicates this, the server responds with a denied (http 401) error for any resource located in one of designer created folders. This is a publishing site and the Pages item and various other items work that are not in this folder.
Any thoughts on how to debug or proceed with this error? Why would IIS reject a request for the same URL based on the user agent string?
Thanks
