Jquery File Upload – Not sending headers in IE9

I’m using jQuery Fileupload to upload files. Its not sending headers that I set to the server. Why is the Authorization header missing only in IE but passed in chrome?

Here is the code:

upload_photo: function(){
  var url =  '/api/v1/upload';
      url: url,
      dataType: 'json',
      paramName: 'uploadFile',
      beforeSend: function ( xhr ) {
      done: function (e, responseJSON) {
          var id = responseJSON.result.id;
          url = responseJSON.result.url;
          var photo_ids = $("#photo_ids");
          var val = photo_ids.val();
          photo_ids.val(val + id.toString() + ",");
          $(".photothumb-wapper").append('<div class=/"photothumb/" id="post_photo_'+id+'"><div><img  src=/"'+url+'/" /></div><img class=/"thumb-delete photo_delete/" id=/"'+id+'/" title=/"Remove/" src=/"/assets/delete-red.png/"></div>');
      start: function (e, data) {
          $(".photothumb-wapper").append('<div class="photothumb photoprogress" style="border:none"><img src="/assets/ajax-loader.gif" /></div>');
      always: function (e, data) {

var setHeader = function (xhr) {
    xhr.setRequestHeader('Authorization', 'Bearer fdf49c4f1cfgc176eb952f18eeefaec3e7');

Headers passed in IE:

Request             : POST /api/v1/upload HTTP/1.1 
Accept              : text/html, application/xhtml+xml, /*//*

Headers passed in Chrome:

  Accept: application/json, text/javascript, /*//*; q=0.01

This answers my question,

Only browsers with support for XHR file upload support setting custom headers.

As a workaround in old browsers like our dear IE, you could set a cookie with the authentication token when the user authenticate and then get it in the server and verify it the same way you verify the header one. I know that it is not the most elegant solution but it works.
