--http3-only is using HTTP/1.1 #10538

Your expectations are correct. Now to find out why it behaves for you this way... |
|
Do I see this correctly, that you have a |
i think yes cause i build this curl by using below link and i didnt used nghttp2 |
|
it seems to working when i configured curl with nghttp2 but ideally it should work without nghttp2 also right root@ubuntu:
< HTTP/3 200 root@ubuntu:~# curl -vvv -k --http3 -o index.html -# https://127.0.0.1:8443/
< HTTP/3 200 Please feel free to close the issue if you think this is implemeted to work only when configured with nghttp2 |
Refs curl#10538, where using --http3-only in a non http2 build has not effect.

I fixed this in #10544, please have a look. |
Hi @bagder
I am using curl with --http3-only option to download file from nginx server.
From below curl man page and help page i came to know that using --http3 will allow to fall back ,--http3-only will not allow to fallback but seems to be with --http3-only also curl is falling back and using http1.1
man curl:-
--http3-only
sion on its own. Use --http3 for similar functionality with a fallback.
Instructs curl to use HTTP/3 to the host in the URL, with no fallback to earlier HTTP versions.
This option will make curl fail if a QUIC connection cannot be established, it will not attempt any other HTTP version on its own
Tells curl to try HTTP/3 to the host in the URL, but fallback to earlier HTTP versions if the HTTP/3 connection establishment fails
curl --help all :-
--http3 Use HTTP v3
--http3-only Use HTTP v3 only
root@ubuntu:~# curl -# -v -k --http3-only -o index.html https://127.0.0.1:443/

Excpeted is to not fall back to http1.1 and expected result should look something like this below
