Hello!
I'm trying to test open proxies to figure out who to block from my site, but I'd like to do that through a proxy of my own. Using PHP and cURL, how would I go about doing so?
Is this what CURLOPT_HTTPPROXYTUNNEL is possibly used for..?
pseudo code: Server (IP address A) connects to it's own proxy server (IP address B), which forwards the request to connect to a suspected-open-internet-proxy, only showing IP address B to the suspected-open-internet-proxy.
