Isn&#x27;t one of the big performance advantages of HTTP2 multiplexing&#x2F;Server Push?  It&#x27;d be nice if they spent some time talking about how to take advantage of those improvements on their platform.<p>Inside my request handler, I ought to be able to say &quot;If you&#x27;re on HTTP2, push out these files:&quot; and have AppEngine behave accordingly.
