    /**
     * Keep the session from timing out.

     * @return \Symfony\Component\HttpFoundation\Response

    public function drip()
    {
        return response('', 204);

The expression return response('', 204) also could return the type Illuminate\Contracts\Routing\ResponseFactory which is incompatible with the documented return type Symfony\Component\HttpFoundation\Response.
