But that's the entire argument he's making. It's not what I mean. When I go to my web host's sysadmins and say "I need to use https so I can use service workers," I don't mean "I need to use TLS so I can use service workers." I mean what I said. https was once defined as merely http + TLS (well, SSL), but it has now come to be a protocol/scheme that supports things that http does not. One of those, and certainly the biggest, is TLS. But there are other differences.

This is a comparison between http and https. It investigates the reason why https is faster, and makes it clear that the difference is that https means other things besides TLS.
