[TLVPHPUG] HTTP/2 and Asynchronous APIs

HTTP/2 (H2) is coming, and along with it a whole new way of communicating over the web. Connection re-use, prioritization, multiplexing, and server push are just some of the features in H2.

In this talk we'll look at the HTTP/2 protocol, and at how we can use asynchronous request now with HTTP/1.x. We will also look at what asychronous requests and H2 mean for your API and clients in the future.

    I F I E RS • h2 — HTTP/2 over TLS, negotiated via ALPN (Application-Layer Protocol Negotiation) • h2c — HTTP/2 over TCP (plain text), uses an HTTP/1.1 request with a 101 Switching Protocols status response if supported

    /A P P L I C AT I O N - L AY E R _ P R OTO CO L _ N E G OT I AT I O N Application-Layer Protocol Negotiation (ALPN) is a Transport Layer Security (TLS) extension for application layer protocol negotiation. ALPN allows the application layer to negotiate which protocol should be performed over a secure connection in a manner which avoids additional round trips and which is independent of the application layer protocols. It is used by HTTP/2. […] On July 11, 2014, ALPN was published as RFC 7301

    N E G OT I AT I O N ( CO N T. ) • May be an OPTIONS request if concurrency of multiple requests is important • May be any request type (e.g. PUT/POST/GET/HEAD/DELETE) but any body must be sent in it's entirety before HTTP/2 can start • A server must ignore an "h2" token in an Upgrade header field. Presence of a token with "h2" implies HTTP/2 over TLS, which is instead negotiated via TLS-ALPN • It must include a settings payload with the initial request
