WebTransport: The Next-Gen Web Protocol

WebTransport supercharges web comms by letting you run multiple, secure streams—both reliable and “best-effort” unreliable—over HTTP/2 and HTTP/3. Think of it as WebSockets on steroids: you get true bidirectional connections (no longer just client-initiated), TLS everywhere, ultra-low latency, and the ability to mix data types in one pipe.

In the video deep-dive, Hussein Nasser walks through why WebTransport fixes WebSocket and gRPC pain points, how it piggybacks on existing HTTP/2/3 infrastructure (and why it can’t run over HTTP/1.1), the demise of HTTP/2 push, the magic behind Extended CONNECT, backfill tricks, and even proxying tips—all in a neat, informal tour through modern web transport.
