I want to check if a page returns the status code 401. Is this possible?

Here is my try, but it only returns 0.

$.ajax({
    url: \"http://my-ip/tes

    Use the error callback.

    For example:

    jQuery.ajax({'url': '/this_is_not_found', data: {}, error: function(xhr, status) {
        alert(xhr.status); }
    });
    

    Will alert 404
