Introducing HTTP/3 Prioritization
Today, Cloudflare is very excited to announce full support for HTTP/3 Extensible Priorities, a new standard that speeds the loading of webpages by up to 37%. Cloudflare worked closely with standards builders to help form the specification for HTTP/3 priorities and is excited to help push the web forward. HTTP/3 Extensible Priorities is available on all plans on Cloudflare. For paid users, there is
RFC 9114: HTTP/3
Internet Engineering Task Force (IETF) M. Bishop, Ed. Request for Comments: 9114 Akamai Category: Standards Track June 2022 ISSN: 2070-1721 HTTP/3 Abstract The QUIC transport protocol has several features that are desirable in a transport for HTTP, such as stream multiplexing, per-stream flow control, and low-latency connection establishment. This document describes a mapping of HTTP semantics o
HTTP/3 From A To Z: Core Concepts — Smashing Magazine
After almost five years in development, the new HTTP/3 protocol is nearing its final form. Earlier iterations were already available as an experimental feature, but you can expect the availability and use of HTTP/3 proper to ramp up over in 2021. So what exactly is HTTP/3? Why was it needed so soon after HTTP/2? How can or should you use it? And especially, how does it improve web performance? Let
QUIC is now RFC 9000
QUIC is now RFC 9000QUIC is a new latency-reducing, reliable, and secure internet transport protocol that is slated to replace TCP, the most commonly used transport today. We’ve talked before about how we love QUIC and are deeply invested in making it a success because it aligns with our mission to build a faster, more resilient, and more trusted internet. In fact, we believe so much in the promis
HTTP/3はどうやってWebを加速するか？ TCP、TLS、HTTP/2の問題とHTTP/3での解決策～Fastly奥氏が解説（後編）
HTTP/3はどうやってWebを加速するか？ TCP、TLS、HTTP/2の問題とHTTP/3での解決策～Fastly奥氏が解説（後編） Webの世界では新しいHTTPの標準として「HTTP/3」の策定が進み、現在最終段階にあります。このHTTP/3はこれまでのHTTPをどのように改善し、高速化を実現していくのでしょうか。 2020年11月25日と26日にオンラインで開催されたFastly Japan主催のイベント「Yamagoya Traverse 2020」のセッション「Webを加速するHTTP/3」で、同社の奥一穂氏がHTTP/3の解説を行っています。 本記事では奥氏のセッションをダイジェストで紹介します。（本記事は「HTTP/3はどうやってWebを加速するか？ TCP、TLS、HTTP/2の問題とHTTP/3での解決策～Fastly奥氏が解説（前編）」の続きです） サーバプッシュの
Head-of-Line Blocking in QUIC and HTTP/3: The Details
Robin Marx is a Web Performance and network protocol researcher at Hasselt University, Belgium. He is mainly looking into HTTP/3 and QUIC performance, and develops the qlog and qvis tools to make this easier. In a previous life he was a multiplayer game programmer and co-founder of LuGus Studios. YouTube videos of Robin are either humoristic technical talks or him hitting other people with longswo

Comparing HTTP/3 vs. HTTP/2 Performance
We announced support for HTTP/3, the successor to HTTP/2 during Cloudflare’s birthday week last year. Our goal is and has always been to help build a better Internet. Collaborating on standards is a big part of that, and we're very fortunate to do that here. Even though HTTP/3 is still in draft status, we've seen a lot of interest from our users. So far, over 113,000 zones have activated HTTP/3 an

Introduction · HTTP/3 explained
This book effort was started in March 2018. The plan is to document HTTP/3 and its underlying protocol: QUIC. Why, how they work, protocol details, the implementations and more. The book is entirely free and is meant to be a collaborative effort involving anyone and everyone who wants to help out. A reader of this book is presumed to have a basic understanding of TCP/IP networking, the fundamental
