HTTP/2 really doesn't belong in that basket. One of these things is not like the others.

CharlieDigital • Apr 12, 2025 • View on HN

You just use HTTP/2. It's a solved problem.

What about HTTP/3 for your second point?

shepherdjerred • Oct 10, 2023 • View on HN

Are you suggesting that we didn't need HTTP2? What's the real alternative here?

jtsiskin • Nov 23, 2021 • View on HN

It’s not: https://en.wikipedia.org/wiki/HTTP/2

I would imagine that once HTTP/2 becomes a serious implementation, this kind of thing will be unnecessary.

kabirgoel • Jul 17, 2022 • View on HN

Yep, although on HTTP/2 this shouldn't be an issue anyway.

Hadn't this been superseded by HTTP/2 formalised just last month?

wmf • Oct 31, 2014 • View on HN

Nobody's taking HTTP/1.1 away.

HTTP2 can reduce this significantly.
