7. HTTP is Everywhere
8. HTTP is Everywhere • The web is HTTP. • Many of you work with the web. • Your jobs depend on HTTP.
9. HTTP is Imperfect
10. HTTP is • Complicated • Inefficient • High latency
11. HTTP is Holding Us Back
12. What’s The Solution?
13. New Protocol! • From the IETF • HTTPBis WG starts discussion in 2012 • Based on SPDY
14. HTTP/2
15. Binary • Text protocols are easy to debug but complex to parse • Binary is simpler. • Simpler (usually) means faster
16. Efficient • Multiplexing (with priority and flow control) • Header compression (HPACK) • Early stream termination. • Server Push
17. Imperfect
18. HTTP/2 is Imperfect • Designed quickly. • Based on SPDY. • Designed primarily for browsers
19. HTTP/2 is Imperfect • Difficult to reason about • Challenging to debug • Awkward edge cases • Inherently concurrent
20. Play
21. Implementations • hyper (Python, client) • nghttp2 (C, client and server) • Firefox (Browser) • curl/libcurl (client)
22. hyper • Actively developed. • Come help! • github.com/Lukasa/hyper • hyper.rtfd.org/en/development
23. Further Reading • http2-explained.rtfd.org • http2.github.io
