Privoxy/Tor with socks4 forwarding

Hi friends,

I am coding an application in which I have to use the privoxy as reverse proxy(http proxy).

The situation is that I have two computers that are connected to internet.
They have different geographical location.

Now computer A has to use the computer B as http proxy but a reverse one using privoxy.

its like privoxy is listening on port 8118 locally for any connections on computer A and whenever it finds any connection it forwards the socks4 connection locally(computer A) on port 9050. But now I dont know how to forward it to computer B to create a tunnel. I mean now I have to use the computer B as http proxy. So is it like that I have to install a sock4 proxy on computer B . Then this sock4 proxy on computer B is like a http proxy.

I am pretty confused. Please help me out...

Note: Privoxy is tool for proxy the things up. Use google to search more on it.

Thanks.
