TL;DR

WebTransport is the newest way to get real-time, bidirectional chats and streams over HTTP/2 and HTTP/3—think WebSockets on steroids. It multiplexes both reliable and “fire-and-forget” streams in one TLS-secured connection, fixes gRPC’s inflexibility and WebSocket’s head-of-line blocking, and finally lets servers push data whenever they want.

In the video you’ll learn how the extended CONNECT handshake works, why HTTP/2’s old server-push never took off (and how WebTransport does it better), the quirks of doing unreliable streams on H2 vs. H3, proxying tips, and even why YouTube still can’t nail notifications.
