I have nginx to forward traffic to certain site, example config:server {  listen 80;    server_name *.company.com;      location /CentOS/7.2.1511/x86_64 {      proxy_pass http://mirror.centos.org/CentOS/7.2.1511/os/x86_64/;        }}This config is working if nginx has a direct internet connection. But I have to use http proxy server to access to Internet. What is the correct config to use http proxy in this situation.
HTTP Proxy behind nginx
