Ilya Grigorik is back again — this time we're talking about his true passion, internet plumbing, web performance, and the HTTP/2 spec. We cover everything around HTTP/2, the spec, HTTP/1 history, SPDY, binary framing layer, the semantics of HTTP/2, pipelining, multiplexing, header compression (HPACK), server push, TLS, "time to glass", upgrading, adoption, support, and more.
