In November 2025, Adam Murdoch enhanced the netty/netty repository by implementing support for the :protocol pseudo-header in the HTTP/3 codec, enabling Extended CONNECT requests as defined in RFC 9220. He introduced a PROTOCOL enum, a protocol() API, and integrated these changes into DefaultHttp3Headers using Java. Adam also improved header validation in Http3HeadersSink to distinguish between Regular and Extended CONNECT, ensuring correct protocol handling. This work enables applications to use WebTransport and WebSocket over HTTP/3, broadening client compatibility while maintaining backward compatibility. His contributions demonstrate depth in network programming, HTTP/3, and real-time communication technologies.
