// -- setcookie() 
// The cookieName and cookieValue arguments are mandatory but all other arguments are optional. 
// expires - (optional) is a Date object. 
// path - the part of the document tree on the server that the cookie is valid for. 
// domain - allows multiple server hosts to be used. 
// secure - boolean and only applicable for use with HTTPS: connections. 
// Example... 
// var today = new Date(); 
// var expires = new Date(today.getMilliseconds() + (10 * 86400000)); // +10 days 
// setcookie('foo', 'bar', expires, '/');
