The HTTP/2 spec has been out for almost two years now, yet adoption has been (predictably) slow. With more and more companies putting a high priority on performance, it’s time to take a serious stand against high load times and rid ourselves of jank once and for all. We’ll start with a brief history of the HTTP protocol, fall into the HTTP/2 spec itself to figure out what’s new, and finally learn how to enable this protocol on our own websites. This talk will cover browser support, server support, and CDN support, as well as how to cleanly overcome HTTP/1.x performance hacks like spritesheets and file concatenation.
