OData.read not working in IE (missing headers, no data) - works in Firefox

Question

I have a SAP Gateway system where I create OData services which I consume in a jQuery HTML5 page.

When doing the HTML page, I always used Firefox to run it. Now I want the users to test the application and SAP automatically uses IE (I have IE 10 installed).

The exact same request, send through OData.read function (datajs library), does not give me any results in IE but in Firefox it does. I reach the success callback function but there is also no result. That's anyhow for one of the services. Another service that I call simunltaneously does give me back results just like Firefox does. Strange thing is that in the success callback function the header (object) in IE is empty but when debugging with IE I do have a response header.

The way I tested was using eclipse and localhost. Firefox works, IE doesn't.

I really have no idea how to fix this and appreciate any help!

My request JS:

var request = {
    headers: {
        'DataServiceVersion': '2.0',
        'X-CSRF-Token': 'Fetch' // needed for update requests
    },
    recognizeDates: true,
    enableJsonpCallback: true,  // didn't have it for Firefox, added for IE but didn't help
    requestUri: requestURL      // URL is definatelly correct and works in the 2nd request
};
OData.read(request, successCallback, displayError);

Request headers according to Firefox:

But the object is empty:

executeRead(url, function (resData, response) {
  // trying to get x-csrf-token but the whole response.header is empty
  cCSRF = response.headers['x-csrf-token'];
  ...
}

response Object
