Field Detail

AUTO_STREAM_FLOW_CONTROL

public static final ChannelOption<Boolean> AUTO_STREAM_FLOW_CONTROL

When set to true Http2WindowUpdateFrames will be automatically be generated and written for Http2StreamChannels as soon as frames are passed to the user via ChannelPipeline.fireChannelRead(Object). If the user wants more control on when a window update is send its possible to set it to false. In this case the user is responsible to generate the correct Http2WindowUpdateFrames and eventually write these to the channel.

See RFC9113 5.2. Flow Control for more details.
