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.
