ALPS and TLS 1.3 half-RTT data

[David Benjamin <[e-mail]>]

Hi TLS and HTTP friends,

At the last HTTPWG interim, there was a question of why one would want
something like ALPS (draft-vvv-tls-alps) for HTTP SETTINGS
(draft-vvv-httpbis-alps) over TLS 1.3 half-RTT data. I know we've also had
some discussion on this topic in the TLSWG as well. At the HTTP meeting,
folks suggested writing up what a half-RTT-based mechanism might look like,
so I put together an I-D below. I hope it helps clarify some of our
thinking.

(The I-D is not meant for adoption or publication or anything. I figured an
I-D was probably the most familiar format for folks.)

David
