    //         any valid string characters.
    //    [expires] - Date object containing the expiration data of the cookie.  If
    //         omitted or null, expires the cookie at the end of the current session.
    //    [path] - String object indicating the path for which the cookie is valid.
    //         If omitted or null, uses the path of the calling document.
    //    [domain] - String object indicating the domain for which the cookie is
    //         valid. If omitted or null, uses the domain of the calling document.
    //    [secure] - Boolean (true/false) value indicating whether cookie
    //         transmission requires a secure channel (HTTPS).

    //  value and path, you would code:

    //  Note that trailing omitted parameters do not require a placeholder.
    //
    //  To set a secure cookie for path "/myPath", that expires after the
    //  current session, you might code:
    //
    //      SetCookie (myCookieVar, cookieValueVar, null, "/myPath", null, true);
