How HTTP/2 Is Changing Web Performance Best Practices | Voxxed

How HTTP/2 Is Changing Web Performance Best Practices | Voxxed: "The Hypertext Transfer Protocol (HTTP) underpins the World Wide Web and cyberspace. If that sounds dated, consider that the version of the protocol most commonly in use, HTTP 1.1, is nearly 20 years old. When it was ratified back in 1997, floppy drives and modems were must-have digital accessories and Java was a new, up-and-coming programming language. Ratified in May 2015, HTTP/2 was created to address some significant performance problems with HTTP 1.1 in the modern Web era. Adoption of HTTP/2 has increased in the past year as browsers, Web servers, commercial proxies, and major content delivery networks have committed to or released support.

Unfortunately for people who write code for the Web, transitioning to HTTP/2 isn’t always straightforward and a speed boost isn’t automatically guaranteed. The new protocol challenges some common wisdom when building performant Web applications and many existing tools—such as debugging proxies—don’t support it yet. This post is an introduction to HTTP/2 and how it changes Web performance best practices."
