HTTP/2 (h2), the successor to HTTP/1.x (h1), started to gain significant mainstream support with service providers such as CDNs during 2016. A major design goal of h2 is improved performance over h1 and some of the optimisations it makes include: HTTP header compression (via HPACK) — reduces the volume of data transmittedA binary (rather than text-based) protocol — faster and simpler to interpret

push_payloads_userland.md Background One of the biggest missed opportunities thus far with HTTP/2 ("H/2") is that we are not yet able to sunset WebSockets in favor of H/2. Web Sockets and H/2 both support multiplexing messages bi-directionally and can send both textual and binary data. Server Sent Events ("SSE"), by contrast, are not bi-directional (they're a "server-push-only" channel) and binary
Delivering CSS & JS on your websites is completely different with HTTP/2, and here is a guide on how I've done it.

We have been hearing about HTTP/2 for years now. We've even blogged a little bit about it. But we h
A few minutes ago I opened the initial pull-request that would provide an implementation of HTTP/2 for Node.js core. While it’s far from being production ready, this marks a key milestone. Because this is just a pull-request, it’s possible to play around with, but there are a few additional steps. First, you’ll need to make sure you’re set up for building Node.js locally by following the instructi
HTTP/2 server push is a performance optimization included in version 2 of the HTTP protocol. All secure traffic through Netlify’s servers has been using HTTP/2 since early 2016. It’s important to understand that HTTP/2 requires secure connectivity. Only websites with HTTPS enabled can take advantage of HTTP/2 and its performance optimizations, like server push and header compression. Currently, 60

Why FastlyProductsServicesSolutionsDevelopersPartnersResourcesPricing Optimizing HTTP/2 server push with FastlySince we made HTTP/2 generally available in November 2016, h2 traffic has been steadily growing as more customers migrate to the new version of the protocol; since the beginning of 2017, h2 traffic has increased by over 400% and h2 requests now make up more than 25% of the total requests
"HTTP/2 push will solve that" is something I've heard a lot when it comes to page load performance problems, but I didn't know much about it, so I decided to dig in. HTTP/2 push is more complicated and low-level than I initially thought, but what really caught me off-guard is how inconsistent it is between browsers – I'd assumed it was a done deal & totally ready for production. This isn't an "HTT
In this article, Jeremy Wagner will teach you everything about server push, from how it works to the problems it solves. Server push allows you to send site assets to the user before they’ve even asked for them. It’s an elegant way to achieve the performance benefits of HTTP/1 optimization practices such as inlining, but without the drawbacks that come with that practice. Jeremy will also show you
Golang 1.8 was released with HTTP/2 server push feature. Golang updated net/http package to support HTTP/2 feature at 1.6 and that code already supported PUSH_PROMISE frame that is used for server push, but 1.6 didn’t have API to spawn that frame. And then, 1.8 contains that API finally. How to Use Server Push?http.ResponseWriter has an unique characteristic. The structure behind http.ResponseWrit
A note from the editors: This article is part one of a two-part series exploring the new HTTP/2 protocol and using it responsibly. Be sure to read part two, Considering How We Use HTTP/2. With HTTP/2 ticking up steadily in use, it’s clear that there’s something to this long overdue update to the protocol. Implementing it, however, not only changes how websites are delivered to the user, it demands
How Backplane Agents phone home using HTTP/2 Backplane is designed to make routing, shaping, and securing network traffic easy and safe, for every application in any environment. One of the key aspects of Backplane’s design that makes this all possible is based on an extension to the HTTP/2 protocol extension that we call h2s. In this post I’ll tell you a little bit about h2s, and describe three o
