The Route to HTTP/2
summary
HTTP/2 arrives as a binary protocol with HPACK header compression that cuts redundant headers by roughly 66% and multiplexing plus priority/dependency frames that eliminate head‑of‑line blocking. It adds server push to proactively send CSS/JS, and browsers like Chrome and Firefox enable it by default. Adoption sits around ~60% of browsers and ~15–20% of top 10k sites; old hacks like spriting, concatenation and domain sharding start slowing pages rather than speeding them.
