HTTP/3

[fiodinggo]

Hello @essen , i 'll try to create http/3, but doesnt work. the server always running, but doesnt access by browser. and this is my code

start(_Type, _Args) ->
    Dispatch = cowboy_router:compile([
        {'_', [{"/", hello_handler, []}]}
    ]),
    TransOpts = #{
        socket_opts => [
			{port, 8181},
            {certfile, "/ssl/cert.pem"},
            {keyfile, "/ssl/key.pem"}
        ]
    },
    Lst = cowboy:start_quic(
        h3,
        TransOpts, 
        #{
            env => #{dispatch => Dispatch}
        }
    ),
	io:format("Listener ~p~n", [Lst]),
	{ok, Listener} = Lst,
	Port = quicer:sockname(Listener),
	io:format("Port ~p~n", [Port]),
	persistent_term:put({cowboy_quic, h3}, Listener),
    qtrial_sup:start_link().

i use cowboy master for that
it is wrong or not?
thanx before.

Assuming your certificate paths are correct, in order to make browsers connect you need more than that. You need:

• a TLS listener with an alt-svc header;
• or a special DNS field for alt-svc;
• or to force the browser to use QUIC (varies depending on browser, Chrome has a command line flag for example)

Getting something like curl to work is simpler but you likely will need to compile it manually. https://curl.se/docs/http3.html

thanks @essen
i will try to.
For placement, will it be placed in the option or in the header on the handler?

[essen]

There's no option at this point.
