Hi David:
Thank you for bringing up this point. A proposal for extending SDCH
to include HTTPS traffic would be most welcome.
This is a change that may have non-obvious security implications, so
the more voices that participate in the discussion, the better. Your
point about encrypting stored dictionaries is a good one. Another
point that has been raised is that the client should not allow HTTPS
traffic to be encoded using a dictionary that was downloaded using non-
secure HTTP.
Saludos,
lincoln
