Mostly true, yet there's that little bit that makes it not total truth.
HTTP/2 has push, where instead of waiting for a browser to decide which
elements to fetch a server can send anything it likes, the basic theory
being that "everyone" will request certain/all objects so sending them
without waiting for the requests will enhance performance. HTTP/2 --
derived from / started as SPDY -- became a standard in May and is
supported by various servers and clients.
WebSockets should probably be mentioned as well.
And the even older content replacing push (ca '95) -- though seldom used
it is still supported by some browsers.
