I saw Google search set the alt-svc header, with QUIC version 39 in header string.

alt-svc: hq=":443"; ma=2592000; quic=51303431; quic=51303339; quic=51303338; quic=51303337; quic=51303335,quic=":443"; ma=2592000; v="41,39,38,37,35"

I'm using Google Chrome Canary which supported QUIC 39. But when I open Google, it still working on HTTP/2 and not on QUIC + HTTP/2.

I set the alt-svc header with QUIC for my website, and it worked.

alt-svc: quic=":443"; ma=7776000; v="39"; persist=1

So I confirm my browser is fine, but what's wrong with Google search?

Chrome is still an opt-in feature. Is it enabled in chrome://flags enable-quic ?

  • Yes, I enabled it, but still not working. It seems like Google Chrome Canary doesn't support `hq` in `alt-svc` header. – jinliming2 Feb 11 '18 at 15:44
