// 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, '/');
