HTTP tunnel module

HTTP tunnel module

The module handles CONNECT requests and establishes a tunnel to a
backend.

Example config:

http {

    map $request_port $allow_port {
        80             1;
        443            1;
    }

    map $host $allow_host {
        hostnames;

        example.com    1;
        *.example.org  1;
    }

    server {
        listen 8000;

        resolver dns.example.com;

        if ($allow_port != 1) {
            return 403;
        }

        if ($allow_host != 1) {
            return 403;
        }

        tunnel_pass;
    }
}
