The most use cases for http/2 server push is to pre-emptively push assets files (such as javascript and css files) to browser. I am wondering can http/2 server push be used to send dynamic payload such as JSON documents to client application? From the [http2-spec](http://http2.github.io/http2-spec/index.html#PushResources), it doesn't mention anything about this. Can anyone elaborate more on this? Why or why not?
