How to configure Nginx behind a corporate proxy

Question

Is there an equivalent of apache's ProxyRemote directive for NginX?

So the scenario is I am behind a corporate proxy and I want to do proxy passes for various services with NginX. I would do it in Apache with the following:

ProxyPass /localStackOverflow/ https://stackoverflow.com/

ProxyPassReverse /localStackOverflow/ https://stackoverflow.com/

ProxyRemote https://stackoverflow.com/ http://(my corporate proxy IP)

I know I need the proxy_pass directive in NginX but can't find what I would use for the ProxyRemote.

Thanks

Not sure how @tacos response can work - possibly something I'm missing but the only way I could sort of get this to work was by rewriting the url and passing on to the corporate proxy. This is shown below:

http {
  server {
    listen 80;
    location / {
          rewrite ^(.*)$ "http://www.externalsite.com$1" break;
          proxy_pass http://corporate-proxy.mycorp.com:8080;
    }
  }
}

This works, but does rewrite the url, not sure if this is important to the original use-case..

The servers you proxy behind an Nginx front-end web server are referred to as upstream servers. You will want to refer to the documentation for the HttpUpstreamModule. It's very similair to what you are familiar with. If you don't need load-balancing, you just setup the one upstream server in the configuration and it will serve your purpose.
