Cookies


Haven't found a standard way to work with cookies, so here's a way to READ a cookie, based on jQuery's cookie plugin :

Read a cookie

function jQuery_trim( text ) {
    return (text || "").replace( /^\s+|\s+$/g, "" );
};
function get_cookie(r, name) {
    // Based on jQuery cookie plugin by Klaus Hartl
    var cookieValue = '';
    var cookies = r.connection.request.headers['Cookie'][0].split(';');
    for (var i = 0; i < cookies.length; i++) {
        var cookie = jQuery_trim(cookies[i]);
        if (cookie.substring(0, name.length + 1) == (name + '=')) {
            cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
            break;
        }
    };
    return cookieValue;
};
then in URL response (see URLs):
function other_page(r) { 
   var cookie_value = get_cookie(r, 'cookie_name');
