The power of HTTP headers and examples

Cool article. Do these headers change with HTTP 1, 2, 3? Or are these headers fixed but only the type of connection changes with different HTTP protocols?

HTTP/1.1 was the last to introduce new headers. HTTP/2 and later specify lower-level details than headers themselves.

I think it's more clear to say that headers are usually specified separate from the protocols these days, so there are new headers introduced after HTTP/1.1, but they are not usually introduced in the core HTTP spec but rather in separate RFCs that usually apply to HTTP/1.1, HTTP/2 and HTTP/3.

The only new header in the HTTP/2 RFC is specifically for HTTP/2 upgrades from HTTP/1.1: https://tools.ietf.org/html/rfc7540#section-3.2.1
