Very nice !

All the tests and benchmarks we see (even if made on real Web sites) are what I call "cold start testing". Basically every is set to 0, we download everything and look at the protocol design impacts on performances. 

But when we talk about better *user* experience, we might want to take into account the impact on performances when the user is doing multiple actions on the same set of resources. HTTP caching enters into play.

Is the performance gain that big? Are there things which can be done in the protocol to take into account longterm usage scenario?
