CORS support for download
Please support CORS access for downloads. Single Page apps need to be signed in constantly and should be able to use refresh tokens AND be able to download. Currently it is diffcult to build a serious HTML5/SPA for OneDrive.
Every other storage provider supports CORS with refresh-token access
We now support proper CORS headers for download requests in a single-page app. For compatibility with Safari, instead of using the /content URL though, you need to retrieve the downloadUrl property and then request it directly.
