jQuery+AJAX response header

Question

I am trying to read response headers using JQuery and Ajax but not all headers are returned. Only few of them.

$(document).ready(function () {

  $.ajax({
    type: 'POST',
    url:'http://do.convertapi.com/Word2Pdf',
    data: '',
    complete: function(resp){
        alert(resp.getAllResponseHeaders());
         }});

});

Working example: http://jsfiddle.net/tomasr/7jWSv/3/

The server response has CORS header included above, so it should be no problems accessing headers using ajax?

Access-Control-Allow-Origin:*

I would like to read all response headers using ajax, any idea how to do that?

It doesn't matter, I do not get all headers with 200 code response either jsfiddle.net/tomasr/7jWSv/5 — Tomas

It's probably because you are doing a cross domain access which jquery does not use XHR. — Deepak Ingole

@Pilot Please explain more detailed. I thought that CORS is introduced to allow cross domain request and Access-Control-Allow-Origin is used for it. — Tomas

try this type: "GET", async: false, complete: function (XMLHttpRequest, textStatus) { var headers = XMLHttpRequest.getAllResponseHeaders(); } — Deepak Ingole

The problem solved by adding

Access-Control-Expose-Headers

to the server response and listing all headers like this

Access-Control-Expose-Headers: x-header-1, x-header-2, x-header-3

The response header above let Ajax request to read cross domain headers.
