 Set a cookie to client. This will add a new 'Set-Cookie' response header. `key` and `value` are required, all other fields are optional.
 If the same cookie (whole cookie string, e.g. "Name=Bob; Expires=Wed, 09 Jun 2021 10:18:14 GMT; Max-Age=50; Domain=example.com; Path=/; Secure; HttpOnly;") has already been setted, new cookie will be ignored.
