I think this is pretty well covered now.

Oh, sorry, this was referring to protocol details. Gotcha.

Do you think it needs to be present in chapter 11?

Well, the Transfer Protocols section def needs an update because it refers to HTTP as dumb only. I think cleaning it up to include HTTPS smart stuff would be a good idea.
