HTTP/3: the past, the present, and the future

This post announces the general availability of QUIC and HTTP/3 support on the Cloudflare edge network, marking a significant advancement in web performance and reliability. It details the evolution from HTTP/1.0 and HTTP/1.1's limitations (connection overhead, head-of-line blocking) through HTTP/2's stream multiplexing, to HTTP/3's solution using QUIC over UDP. This enables independent stream delivery, faster connection establishment by combining transport and TLS handshakes, and user-space implementation for quicker updates.
