Re: The "trusted" / "explicit" proxy discussion

Mark,

Yes, let's clarify a few things.

If what you are asking for is for people to read up before they post,
well that would be great, but there's a lot of reading.  If what you are
asking for is for people to refrain from discussion on developing
Salvatore's draft, I would take issue with this, because it is directly
relevant to both HTTP2 and the proxy model in general that needs to
evolve if HTTP2 is to be used atop TLS (e.g, with the http: URI).  I
will also add that you yourself have revisited issues, and that this
should be allowed as and when an issue ripens.  We specifically said in
Zürich that we needed to talk about this very thing because proposals
were not yet well developed, especially as regards to user interface.

Doing so will save new folks a lot of time, and save those who have been here longer the need to re-hash old discussions.

That discussion won't be about a particular proposal, but instead about what requirements a proposal must meet, and what constraints it has to operate within.

While discussing this is on-topic for the Working Group mailing list, we can't allow this kind of exploration to distract us from our chartered work -- defining HTTP/2 well and on schedule.

That's not to say that discussion of proxies is prohibited; I'm just concerned about the flood of messages, and am asking for people to think before hitting 'send', because we're entering a critical period of the work on HTTP/2.
