IE 11,XMLHttpRequest和CORS

I'm trying to access an API service (via XMLHttpRequest/ajax) hosted on a sub-domain (ie: a client on app.samedomain.com will call out to api.samedomain.com) that requires specific headers to be set for security purposes, but I keep getting Access is denied errors. All the solutions I've found say the client/end user must add the site to the "Trusted Sites" security zone, but obviously this is not a real solution. What do I need to do to access an external site with specific headers?

Example Code:

var getUserById = function (user, callback, error) {
  $.support.cors = true; 
  var endpoint = _getApiVersion() + '/person/model/' + user.userId;
  var _headers = _setHeaders(endpoint, null, user, 'GET');
  $.ajax({
    type: 'GET',
    beforeSend: function (request)
    {
      request.setRequestHeader("api-key", _headers['api-key']);
      request.setRequestHeader("timestamp", _headers['timestamp']);
      request.setRequestHeader("content-md5", _headers['content-md5']);
      request.setRequestHeader("content-type", _headers['content-type']);
      request.setRequestHeader("signature", _headers['signature']);
      request.setRequestHeader("Access-Control-Allow-Origin", "*");
    },
    url: _getBaseUrl() + endpoint,
    data: null,
    contentType: 'application/json',
    dataType: 'json',
    success: callback,
    error: error
  });
};

Thanks in advance,
Dan

    Are you trying to get data that is not in the same domain as the requester? If that is the case the only option is to proxy the original request via a service so XMLHttpRequest has access to it.
