Question

I have a $.ajax request on the same domain and I want to read the cookie. It keeps returning null.

$.ajax({
    type: 'GET',
    url: myUrl,
    success: function(output, status, xhr) {
        alert(xhr.getResponseHeader("MyCookie"));
    },
    cache: false
});

Any ideas? I’m using Chrome for this.

Answer 1

You’re looking for a response header of Set-Cookie:

xhr.getResponseHeader('Set-Cookie');

It won’t work with HTTPOnly cookies though.

Update

According to the XMLHttpRequest Level 1 and XMLHttpRequest Level 2, this particular response headers falls under the "forbidden" response headers that you can obtain using getResponseHeader(), so the only reason why this could work is basically a "naughty" browser.
