Large latency increase when using a resolver for proxy_pass

[user384829]

Hi Maxim,
Thanks for the reply.

What about if we used a stream/tcp proxy_pass with resolver? Something like
this:

resolver 8.8.8.8 8.8.4.4 ipv6=off; 

stream {
  server { 
    listen localhost:81; 
    set $upstream_host my.upstream-host.com;
    proxy_pass $upstream_host:443; 
  } 
}

server { 
  listen 80; 
  location ~ /api/ { 
    rewrite /api/(.*) /$1 break;
    proxy_ssl_verify off; 
    proxy_pass https://localhost:81; 
  } 
} 

Would this work?
Thanks,
Max
