Nginx as a forward proxy?

Server NGINX
1

Hey Folks,

I was wondering if it would be possible to use nginx as a forward proxy.
I’m currently using tinyproxy on a project but it seems to have some
issues leaking connections, so I’m looking for alternatives. Since I’ve
used nginx for other projects, I thought I would muck around with it.

So I have a basic, naive config that doesn’t work.

    location / {
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded_for $proxy_add_x_forwarded_for;
     proxy_set_header Host $http_host;
     proxy_redirect false;
     proxy_max_temp_file_size 0;

     proxy_pass http://$host$uri;
    }

Before I fire up the packet sniffer, is what I’m trying to do even
possible with nginx?
