How to setup haproxy to connect to backend server using HTTP/3 QUIC?

cm flag

I am able to configure HAProxy to to present itself as an HTTP/3 server by following instruction here: https://www.haproxy.com/blog/announcing-haproxy-2-6/

bind :443 ssl crt server.pem alpn h2,http/1.1
http-response set-header alt-svc "h3=\":443\";ma=900;"

But what do I need to put in haproxy.cfg to to indicate to HAProxy that the backend server supports HTTP/3 and it should use QUIC protocol to connect to it? I tried the same quic4@ prefix but it didn't seem to do anything.

There is nothing about this in haproxy documentation. You probably want to ask this question on https://discourse.haproxy.org/ or on their mailing list https://www.mail-archive.com/[email protected]/

You need this line also to enable quic protocol ;

# enables HTTP/3 over QUIC
bind quic4@:443 ssl crt /etc/haproxy/certs/foo.com/cert.pem alpn h3

This is for the frontend. The question is about the backend.

Also, Haproxy needs to be compiled with QUIC flag. The one I installed doesn't come with QUIC enabled.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
