As a developer I am very excited about the next version of HTTP/3.0. I noticed some time ago that when I opened Google.com then I could see in Devtools > Network that the protocol appeared as Quic. But now when I open it I only see h2 instead. Why is that?
I also noticed that the alt-svc header indicates that the resource is also available over quick. But it's still loading over h2.
alt-svc: quic=":443";
I noticed the same thing using curl, that the protocol used is h2 not h3. But Google has been using Quic for years now. Why this change?
curl -v https://www.google.com/
* ALPN, offering h2
* ALPN, offering http/1.1
* ALPN, server accepted to use h2
* Using HTTP2, server supports multi-use
* Connection state changed (HTTP/2 confirmed)
> GET / HTTP/2
> Host: www.google.com
> User-Agent: curl/7.61.1
> Accept: */*
