How to use http1 and http2 on the same nginx server with virtual hosts?

Question

Nginx

Good day, actually the question is how to use http1 and http2 on the same nginx server with virtual hosts? If you specify listen 443 ssl http2 on one virtual host, then all domains automatically switch to http2, how to separate them? please share your experience

Answer 1

So you try to connect with HTTP/1.1 - it also works by default for clients that don't know how to 2.0.
