How can I set up a proxy on my server? I don't mean a Glype proxy where there is an web form in which you enter a URL. What I mean is something like one that's listed here, where you can enter IP address and port.
How do I set up my server for this?
I need this so my PHP script on another server can connect through that server like
$proxy = 192.155....:80 and then use that to handle GET and POST requests.
