SPDY is a layer below HTTP that makes HTTP go faster by multiplexing multiple HTTP request/response pairs over a single socket.

There's nothing fake about the HTTP request / response pairs.

> Are you saying that SPDY prioritization is specified in terms of top frames, subframes, scripts and such? The Web part of prioritization that deals with those should obviously (to me) be handled by WebCore.

I'm saying that the mapping of those HTML concepts to priorities differs in different scenarios.  Certainly holding request in WebCore is counter-productive in cases were the networking library can make better prioritization decisions than WebCore.

In some sense, you can compute a more optimal prioritization of requests when you have as much information available as possible.  In some cases, some of that information is transport-specific and so only exists at the lower layers of the network stack.
