2.6 Viewer IE 11 CORS Error (Request header x-requested-with not present). Working fine in Chrome, Firefox, & Safari

I'm having trouble using the 2.6 viewer in IE 11.  I have followed the CORS configuration, specifying the appropriate host servers, and I am able to view the page in Chrome, Firefox, and Safarind Safari.  When in IE, I see an error in the Console log: a "Request header x-requested-with was not present in the Access-Control-Allow-Headers list".  This is odd because those headers are present in the other browsers (inspecting headers with developer tools), and the cross domain files are downloaded (desktop.js etc).  Any suggestions?

  Still looking for any answers or suggestions for IE11 to work with CORS with 2.6.1 viewer when HTML viewer and Essentials sites are on different servers.  Does anyone have an example site that it is working correctly?  Like I mentioned, the other browsers are working perfectly.  I can use developer tools to monotor headers, and everything looks ok there.  Not sure what the issue is.

  I've resolved this with LatGeo Tech Support.  You need to modify the RestAppSettings file to look like this (bascically concatenate the header list):

   

      <AllowHeaders>

   

        <Header Name="Content-Type, X-Requested-With" />

   

      </AllowHeaders>
