public class Http2ForwardStreamChildInitializer extends io.netty.channel.ChannelInitializer<io.netty.handler.codec.http2.Http2StreamChannel>
Per-stream child initializer used with Http2MultiplexHandler on the NettyHttpClient forward path. It mirrors the HTTP/1.1 forward pipeline built by HttpClientInitializer.configureHttp1Pipeline(io.netty.channel.ChannelPipeline) but on an HTTP/2 stream channel, so a streamed upstream response (Server-Sent Events) is relayed incrementally instead of being aggregated to completion before its head reaches the proxy client.

An HTTP/2 stream channel is decoded into the same unaggregated HttpObjects that the HTTP/1.1 path produces (Http2StreamFrameToHttpObjectCodec in CLIENT, non-aggregating mode), then the identical shared streaming machinery is reused: HttpContentDecompressor, TimeToFirstByteHandler, StreamingAwareHttpObjectAggregator (which relays text/event-stream / client-requested streams via StreamingResponseRelayHandler and aggregates everything else to a FullHttpResponse), MockServerHttpClientCodec, and the shared HttpClientHandler.

HTTP/2 child channels do NOT inherit parent-channel attributes, so the per-request attributes the forward machinery reads off the channel are copied from the parent to the child in initChannel(io.netty.handler.codec.http2.Http2StreamChannel). A close listener closes the parent connection when the single stream ends, preserving the non-pooled "close after one response" behaviour of HTTP/2 forwards.
