 *  Fix: Don't corrupt the response cache when a 304 (Not Modified) response
    overrides the stored "Content-Encoding" header.
 *  Fix: Gracefully shut down the HTTP/2 connection before it exhausts the
    namespace of stream IDs (~536 million streams).
 *  Fix: Never pass a null `Route` to `Authenticator`. There was a bug where
    routes were omitted for eagerly-closed connections.
