Comment:

e) The guidelines allow the client to go through a first
point-to-point session establishment with the proxy, and if so
desired, through a second end-to-end session establishment with the
server.

Establishing an HTTPS connection is a somewhat heavy process for
wireless devices, requiring the delivery and possibly acceptance of
certificates. A double initiation procedure reduces, rather than
increases, usability at session start.

WG Notes: [Needs to be checked after editorial re-writing] See: http://www.w3.org/2008/10/07-bpwg-minutes.html#item02 Final resolution: - Accept the thrust of Tom's submission on HTTPS, and editor to make sure that the wording is beefed up (e.g. by saying that if a proxy rewrites HTTPS ... rather than saying a proxy MAY) to make it clear that if you _must_ do it the user MUST know and MUST have a choice

Resolution: We have added text to this section that goes some way to addressing your concern
