QUIC Client
TsgcQUICClient — a raw QUIC transport client (RFC 9000): open a connection with a single TLS 1.3 handshake, send and receive bytes over one or many streams, with 0-RTT resumption and connection migration, in Delphi, C++ Builder and .NET.

QUIC without HTTP semantics. Set Host, Port and event handlers, activate the component, then write bytes on a stream. Built on the native OpenSSL 3.5 QUIC engine.
TsgcQUICClient
QUIC (RFC 9000) over UDP, TLS 1.3
Delphi, C++ Builder, .NET
Assign Host and Port, hook the QUIC events, set Active, then send bytes with WriteData. Call EnableMultiStream and OpenStream for several streams on one connection.

Host, Port and Active open and close the QUIC connection; Connect / Disconnect and Start / Stop do it explicitly.
QUICOptions configures ALPN, timeouts and 0-RTT; SSLQUICOptions tunes the TLS 1.3 layer.
EnableMultiStream plus OpenStream(aUnidirectional) put several independent QUIC streams on one connection (builtin engine).
WriteData writes a string or TBytes payload onto a stream.
OnQUICConnect, OnQUICStreamData, OnQUICDisconnect and OnQUICException drive the connection lifecycle and inbound data.
0-RTT resumption and connection migration keep a session alive across a single round trip and across network changes.
