      • getMaxInboundWindowUpdateFramesPerDataFrameSent

        public com.google.protobuf.UInt32Value getMaxInboundWindowUpdateFramesPerDataFrameSent()
         Limit the number of inbound WINDOW_UPDATE frames allowed per DATA frame sent. If the number
 of WINDOW_UPDATE frames received over the lifetime of connection exceeds the value calculated
 using this formula::
     1 + 2 * (inbound_streams +
              max_inbound_window_update_frames_per_data_frame_sent * outbound_data_frames)
 the connection is terminated. The ``http2.inbound_priority_frames_flood`` stat tracks
 the number of connections terminated due to flood mitigation. The default limit is 10.
 Setting this to 1 should be enough to support HTTP/2 implementations with basic flow control,
 but more complex implementations that try to estimate available bandwidth require at least 2.
 [#comment:TODO: implement same limits for upstream inbound frames as well.]

      • getStreamErrorOnInvalidHttpMessaging

        public boolean getStreamErrorOnInvalidHttpMessaging()
         Allows invalid HTTP messaging and headers. When this option is disabled (default), then
 the whole HTTP/2 connection is terminated upon receiving invalid HEADERS frame. However,
 when this option is enabled, only the offending stream is terminated.
 See `RFC7540, sec. 8.1 <https://tools.ietf.org/html/rfc7540#section-8.1>`_ for details.

 Envoy.
 2. SETTINGS_ENABLE_CONNECT_PROTOCOL (0x8) is only configurable through the named field
