Let's say I have two webservers running on https://server:10000 and https://server:10001, that is, SSL termination happens on my server, not on nginx.
I want nginx to route https://server0.mydomain.com to server:10000 and  https://server1.mydomain.com to server:10001
I came up with the following, but how can I match based on hostname?
stream {
    upstream server0 {
        server server:10000;
    }
    server {
        listen 443;
        proxy_pass server0;
    }
}
This doesn't work because, I think, nginx wants to terminate ssl connection, instead of just passing the traffic through?
http {
    upstream server0 {
        server localhost:19080;
    }
    server {
        listen 443;
        location / {
            proxy_pass https://server0;
        }
    }
}
I saw this, https://stackoverflow.com/a/40135151/3515174 but ssl_preread doesn't appear to work on windows.
What are my options?
