Let's say I make a cURL request to http://127.0.0.1/secret.php, having set the cURL options CURLOPT_PROXYTYPE and CURLOPT_PROXY so that it's using a valid, real HTTP proxy server to which I have access and can load any non-localhost URL with successfully.
现在，看来这样的请求失败了，这是有充分的理由的。毕竟，使用代理服务器时，URL转到127.0.0.1可能意味着在代理服务器端出现某种“语法错误”，对吗？但是从理论上讲，代理服务器可能正在运行本地Web服务器，侦听127.0.0.1，那么这将是一个有效的请求吗？
My question is: even though this cURL HTTP request appears to have failed, has the proxy server "seen" my request for http://127.0.0.1/secret.php, even if it didn't process it? Basically, have I revealed the "secret.php" string to a third party by attempting to unsuccessfully load it with a cURL HTTP request using a proxy set in the appropriate cURL options?
我不愿尝试自己弄清楚这个想法，所以我不停地旋转，所以我希望有一个比我聪明的人可以一劳永逸地为我解决这个问题。
