    Cross Site Request Forgery protection
    While the above method can be used for AJAX POST requests, it has some inconveniences: 
    you have to remember to pass the CSRF token in as POST data with every POST request. 
    For this reason, there is an alternative method: on each XMLHttpRequest, 
    set a custom X-CSRFToken header to the value of the CSRF token. 
    This is often easier, because many javascript frameworks provide hooks that allow headers 
    to be set on every request. In jQuery, you can use the ajaxSend event as follows:
    **/
    $('html').ajaxSend(function(event, xhr, settings) {
        function getCookie(name) {
            var cookieValue = null;
            if (document.cookie && document.cookie != '') {
                var cookies = document.cookie.split(';');
                for (var i = 0; i < cookies.length; i++) {
                    var cookie = jQuery.trim(cookies[i]);
                    // Does this cookie string begin with the name we want?
                    if (cookie.substring(0, name.length + 1) == (name + '=')) {
                        cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                        break;
                    }
                }
            }
            return cookieValue;
        }
        if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
            // Only send the token to relative URLs i.e. locally.
            xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
        }
    });
