We are starting to test http3 in our proxies and I found curl doesn't have the same behaviour when printing http_version variable.

When we do it with http/1.1:

$ docker run -it --rm --network test_network $curl curl -sk  https://usvc-ingress:1443/nginx_status -o/dev/null -w '%{http_version}\n'

If we do the same with http/3, it's empty:

$ docker run -it --rm --network test_network $curl curl -sk  --http3 https://usvc-ingress:1443/nginx_status -o/dev/null -w '%{http_version}\n'

The request is working fine with http/3:

$ docker run -it --rm --network test_network $curl curl -sk --http3 https://usvc-ingress:1443/nginx_status -i

I compiled curl from sources using the versions:

ARG CURL_VERSION=curl-7_80_0

From curl -V:

$ docker run -it --rm --network test_network $curl curl -V
