WebTransport is a next-gen protocol riding on HTTP/2 and HTTP/3 that finally fixes the quirks of WebSockets and gRPC. It gives you multiplexed, bidirectional streams—reliable when you need it, “unreliable” for ultra-fast updates—over a single TLS-encrypted connection, all without inventing a brand-new transport layer.
In his deep-dive video, Hussein Nasser breaks down how WebTransport works (and why it won’t run on HTTP/1.1), walks through upgrade paths, and explains why older tricks like HTTP/2 server-push and YouTube’s notification system struggled. Along the way he sprinkles in links to his Udemy courses on backend, networking, and database engineering for anyone who wants to go deeper.
