Hi,

HTTP2 must work in the clear and over TLS. This is required because HTTP1.1 and HTTP2 must coexist to ease the migration to HTTP2, and to accelerate HTTP2 deployments.

Regards
Emile

Objet : Re: HTTPS 2.0 without TLS extension?

... and don't forgot some of the more obscure usage of HTTP, such as HTTP over USB in the USB-IF's IPP USB Specification:

    http://www.usb.org/developers/devclass_docs


There isn't much point in using TLS over USB (and a lot of cost issues for that class of printer against it), and we need to continue to use the same USB end points/interfaces, so upgrade remains an important feature of HTTP/2.0 for me/Apple...

FWIW, it seems reasonable to me to have the spec allow HTTPS 2.0 without TLS extension. If you want to Upgrade, be my guest. I have no plans for my browser to support that, and I don't think Google servers will support it either, because we care strongly about the advantages of TLS-ALPN vs Upgrade.

Not only that, I don't think we can reasonably call this HTTP 2.0 if we have no path to do it in the clear.
