Hello,

I’m trying to basically use nginx as replacement to hitch (for Varnish).

Request goes like this: browser → nginx (stream SSL) → varnish (HTTP2 on) → backend HTTP

stream {
server {
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
proxy_pass 127.0.0.1:6081;
proxy_protocol on;
}
}

With the above, I’m getting HTTP/1.1 in browser.
When I replace nginx with hitch, I get HTTP/2.

From Hitch docs: "Hitch will transmit the selected protocol as part of its PROXY header” Does nginx have same capability?

In general, is nginx capable of being SSL terminator for HTTP/2 backends using TCP streams? (while delivering HTTP/2 to supporting clients). I’m interested in using TCP streams since only those will allow use of PROXY protocol to upstream.

Best Regards,
Danila
