nginx as a reverse proxy, forwarding to a squid proxy server

[robertelee]

Greetings all,

Was wondering if it is possible to configure nginx as a reverse proxy
that forwards to a squid proxy server.

Currently I am using Squid as a forward proxy to another internal Squid
proxy server:
cache_peer internal_squid_proxy parent 8000 0 no-query
cache_peer_access internal_system allow internal_squid_proxy https

I've looked at the reverse proxy SSL write up here:
http://www.cyberciti.biz/faq/howto-linux-unix-setup-nginx-ssl-proxy/

That looks pretty close to what I want to do, except instead of
reversing directly to a web server, I need to reverse to a forward
proxy.

Ie, something like:
location / {
	        proxy_pass  http://internal_squid_proxy;
}


Is there a cache_peer equivalent (instead of proxy_pass) for nginx?

Thank you,

Robert
