HTTP/2
HTTP/2 was the first major update to the main transport protocol of the web in nearly 20 years. It arrived with a wealth of expectations: it promised a free performance boost with no downsides. More than that, we could stop doing all the hacks and work arounds that HTTP/1.1 forced us into, due to its inefficiencies. Bundling, spriting, inlining, and even sharding domains would all become anti-patterns in an HTTP/2 world, as improved performance would be provided by default. This chapter examines how this relatively new technology has fared in the real world.
