JavaScript Getting all response headers from jqXHR get response headers javascript,get response headers,get response headers

On my server (written in Go), I'm sending back a custom header field that I'm trying to read from when I make an ajax call.

$.ajax({
        url: url,
        success: function(data, status, request) {
            console.log("Custom field: " + request.getResponseHeader('Custom-Header')); 

            // doing stuff with data
        }
});

The response

HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Custom-Header: some,comma,separated,stuff,here
Content-Type: text/csv
Date: Mon, 10 Aug 2015 15:42:34 GMT
Content-Length: 1379

This will always return null. I tried using getResponseHeader for regular headers that I've confirmed are in the response packet, such as Content-Length, Date, and Access-Control-Allow-Origin; these all return null as well. The only header that works is Content-Type.

If I use getAllResponseHeaders(), it returns a string with just Content-Type: text/csv.

How do I access other headers that are not Content-Type? I saw that there was a bug related to this 3 years ago, but only affected Firefox. I'm using Chrome v 44.0.2403.130 (64-bit).
