附加信息

The original problem reported (sign-in loop) is actually a known limitation of IWA, which cannot be used via proxy, thus the app tries to authenticate multiple times in a loop. (Note that in 3D proxy or CORS is required to download images because of stricter webgl requirements for rendering images, so this is not a problem in the MapViewer.) To make the Scene Viewer open the service without the proxy using Cross Origin Resource Sharing (CORS) the server must be added to the Trusted Servers list. This however might still not work in IE / Microsoft Edge (but works in all other browsers) due to a bug with their implementation of IWA with xhr: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/11018116/ If users run the Scene Viewer in an updated version of Microsoft Edge with the fix installed, this solution works. We could not find any information about a fix being available for Internet Explorer users.
