Hi Valentin:

Are you talking about the same "push" as I am? HTTP/2, or at least SPDY,
had the ability to *push* content like CSS in advance of the request,
pushing content into the browsers cache *before* it needs it. I'm not
talking about long polling or other technology. I've only read about this
technology, though. I've never seen it implemented in practice. And for
prioritization, it's about choosing to send more important content before
less important content. I don't think you are correct in terms of future
potential here. But, it's very likely that you are correct in terms of
*current* potential. That is, I think this technology is too new for people
to understand it and really think about how to leverage it. It sounds like
you don't even know about it...
