WebBroker + WebSockets + HTTP/2
Cross-platform WebBroker / DataSnap host that also accepts native WebSocket upgrades and HTTP/2 streams on the same TLS port.
Cross-platform WebBroker / DataSnap host that also accepts native WebSocket upgrades and HTTP/2 streams on the same TLS port.
Cross-platform sibling of TsgcWSHTTPWebBrokerBridgeServer with HTTP/2 framing on top — ALPN h2 negotiation handles the upgrade path, your WebBroker handlers stay the same.
TsgcWSHTTP2WebBrokerBridgeServer
Windows, macOS, Linux, iOS, Android
Enterprise
Mount your TWebModule, configure SSLOptions and Specifications.HTTP2, then Active := True — HTTP/1.1, HTTP/2 and WebSocket all share the same TLS endpoint.

end;WebBroker / DataSnap on the OpenSSL Indy stack with HTTP/2 framing — one TLS endpoint, three protocols.
During the TLS handshake the server advertises http/1.1 and h2; the client picks one. WebSocket upgrades still flow over the HTTP/1.1 path.
Multiple HTTP/2 streams share one TCP connection — a single browser tab can issue dozens of REST calls in parallel without HOL blocking.
Each HTTP/2 request is decoded and replayed through the WebBroker pipeline, so existing TWebModule, DataSnap REST and RAD Server handlers work without changes.
Set Specifications.RFC6455 := True to keep WebSocket upgrades on the same port. Bind OnConnect / OnMessage for live channels.
Cross-platform OpenSSL TLS. For Windows-only deployments with kernel-mode TLS use the TsgcWSServer_HTTPAPI_WebBrokerBridge sibling on HTTP.SYS.
For QUIC-based HTTP/3 use TsgcHTTP3Server directly — pair the two when you want HTTP/2 over TCP for legacy clients and HTTP/3 over QUIC for modern ones.
