TsgcHTTP3Server — an HTTP/3 server (RFC 9114) that serves requests over QUIC. It descends from TsgcQUICServer, binds a UDP port, loads a certificate and key, and raises an event for every request, with server push, WebTransport sessions and datagrams, in Delphi, C++ Builder and .NET.
Bind a UDP port, load a PEM certificate and key, and answer each request in OnH3Request. QPACK, server push and WebTransport are built in. Built on the native OpenSSL 3.5 QUIC engine.

HTTP/3 (RFC 9114) over QUIC

The server binds a UDP port, loads a certificate and key, and raises OnH3Request for every request. WebTransport sessions arrive through OnWebTransportSession.

Port and Active bind and release the UDP listener; the server descends from TsgcQUICServer.
QUICOptions.SSLOptions.CertFile and KeyFile load the PEM certificate and private key for the TLS 1.3 handshake.
OnH3Request fires per request with the parsed request; the application fills the response, and can push additional responses from inside the handler.
OnH3TunnelData and TunnelSend(aConnection, …) drive Extended CONNECT tunnels; SendDatagram sends an unreliable datagram.
OnWebTransportSession hands you a WebTransport session (RFC 9220) with its own QUIC streams on the builtin engine.
OnH3Connect, OnH3Disconnect and OnH3Exception report the connection lifecycle and errors.
