This is a really interesting read (linked from that presentation) http://chimera.labs.oreilly.com/books/1230000000545/ch12.html http://chimera.labs.oreilly.com/books/1230000000545/ch12.htm... * one tcp connection per request * Server push functionality / server initiated streams * current implementations means http/2 works over tls _only_ - neither Firefox nor chrome currently support non encrypted connections. This does keep things simpler with things like proxies in the middle I presume also. * tls implementations must now support sni also so basically http/2 is now a forcing function for supporting sni which is awesome.
