HTTP, the protocol that runs the web, is getting an update! The Internet Engineering Task Force (IETF) just released something we’ve collectively been working on for several years: HTTP/3. HTTP/3 leverages a new transport protocol, QUIC, to deliver improved performance on the most challenging networks without compromising performance on great ones. And along the way, these updates change which document you should be referencing for any version of HTTP, not just HTTP/3. \r\n Advantages of QUIC and HTTP/3 \r\n When the QUIC RFCs were published last year, I wrote about the advantages that this new transport could bring to the internet at large . HTTP/3 enables multiplexing and better congestion control, like HTTP/2, but without head-of-line blocking, which reduces performance in the presence of packet loss. HTTP/3 offers fast connection setup, like TCP Fast Open and TLS 1.3 Early Data, but without the tight constraints on the size of that first request.…
