The complete guide to HTTP/2 with HAProxy and Nginx

With the recent buzz around HTTP/2 and its benefits, it is time to upgrade the infrastructure. This article shows how to install and configure HAProxy (with SSL termination) with Nginx. To ease the process even more, I supply you with ready to use Docker images.

TL;DR

Skip to Configuration section if you want to skip installation process and you are only interested in configuration details.

Why should I care about HTTP/2?

There are already many articles out there about HTTP/2 and its benefits - and I encourage you to read them. I'll focus on points which are most important from my point of view.

Key benefits of HTTP/2:

• It is binary (not textual like HTTP/1.1) and uses header compression. No more worries about header and cookies size.
• Is fully multiplexed, can use one connection for parallelism. Your site performs much better in case it includes plenty of resources (fonts, CSS, JS, image files) because now they are all loaded in single TCP connection, in a non-blocking manner. Domain sharding and asset concatenation becomes an anti-pattern. In short: your website loads much faster.
• It allows the server to push responses proactively into client caches (no support for that feature in Nginx yet).
• It uses the new ALPN extension which allows for faster-encrypted connection. The encryption protocol is determined during initial connection.

Haproxy ar trebui eliminat din acel config. Nu aduce nici un beneficiu real si este inca un point of failure. Nginx suporta http2 si poate face load balancing daca este nevoie.

Eu le-as pune invers ca sa poti sa faci direct routing cu backendurile.
