I may be lacking in HTTP and HTTPS knowledge so apologies in advance.

I see that in the response to a curl request, using curl -i, we can see the HTTP version and response code, for e.g. HTTP/2 200. This is returned when the curl request is directed at a HTTPS endpoint (https://xxx).

Would it be possible to see a HTTPS in the response? If not, why not?

CodePudding user response：

No, whether the communication is secure or not has nothing to do with which version of the protocol you are using, in the response you will see the version (commonly HTTP/1.1 or HTTP/2 these days)

Using https means that the connection is established over TLS, while the communication protocol is still HTTP.

In simple terms, TLS is a communication channel, while HTTP is a dialect
