$( function (){
    $( '#user_logout' ).on( 'click' , function (e){
        // HTTPAuth Logout code based on: http://tom-mcgee.com/blog/archives/4435
        e.preventDefault();
        try {
            // This is for Firefox
            $.ajax({
                // This can be any path on your same domain which requires HTTPAuth
                url: "/any/path" ,
                username: 'reset' ,
                password: 'reset' ,
                // If the return is 401, refresh the page to request new details.
                statusCode: { 401: function () {
                    document.location = document.location;
                    }
                }
            });
        } catch (exception) {
            // Firefox throws an exception since we didn't handle anything but a 401 above
            // This line works only in IE
            if (!document.execCommand( "ClearAuthenticationCache" )) {
                // exeCommand returns false if it didn't work (which happens in Chrome) so as a last
                // resort refresh the page providing new, invalid details.
                document.location = "http://reset:reset@" + document.location.hostname + document.location.pathname;
            }
