WebTransport is this supercharged HTTP/2/3-based transport that brings multiplexed, bidirectional, secure streaming (both reliable and unreliable) under one roof—goodbye WebSocket & gRPC limits. Secured by TLS, it offers low-latency data flow for real-time apps and way better client-server comms without the old one-way push headaches.
Plus, it rides on existing HTTP/2 & HTTP/3, uses an Extended CONNECT handshake (so no unreliable streams on HTTP/1.1), and finally explains why HTTP/2 push died and notifications still stink on some services. Bottom line: a game changer for next-gen web comms.
