Notes on HTTP/2

HTTP/2, the successor to SPDY is finally gaining traction on both browsers and web servers. For my own benefit (and hopefully yours), I’ll be documenting relevant articles and information here.

NGINX

HTTP/2 is supported on NGINX as of version 1.9.5. To get it working on my dev environment, I followed the instructions on a couple of different sites (listed below), but needed to run both “brew update”, and then “brew reinstall --devel --with-spdy nginx”. When I tried to just install NGINX using the “--devel” command, I was greeted by a message stating that 1.8.0 was already installed.

Apache

HTTP/2 support is now available in Apache httpd 2.4.17. A great write-up is available at mod_h[ttp]2: how to h2 in apache.

Gotchas

Even though SSL is not enforced in the RFC, all browsers that support HTTP/2 require it. So if you plan on going down the HTTP/2 route, be sure that SSL is an option, or already enabled on your site/app.
