The proxy will read the HTTP headers of your query, forward your request to the destination (with your HTTP headers) and then write the response to you.Example steps :1)HTTP GET / sent to 1.1.1.1 (proxy)2)1.1.1.1 receive request and parse header for getting the final destination of your HTTP request.3)1.1.1.1 forward your query and headers to www.site.com (destination in request headers).4)1.1.1.1 write back to you the response receive from www.site.comWith CURLOPT_HTTPPROXYTUNNELWith CURLOPT_HTTPPROXYTUNNEL : You ask the proxy to open a direct binary connection (like HTTPS, called a TCP Tunnel) directly to your destination by doing a CONNECT HTTP request. When the tunnel is ok, the proxy write you back a HTTP/1.1 200 Connection established. When it received your browser start to query the destination directly : The proxy does not parse HTTP headers and theoretically does not read tunnel datas, it just forward it, thats why it is called a tunnel !Example steps :1)HTTP CONNECT sent to 1.1.1.12)1.1.1.1 receive HTTP CONNECT and get the ip/port of your final destination (header field of HTTP CONNECT).3)1.1.1.1 open a TCP Socket by doing a TCP handshake to your destination 2.22.63.73:80 (ip/port of www.site.com).4)1.1.1.1 Make a tunnel by piping your TCP Socket to the TCP Socket opened to 2.22.63.73:80and then write you back HTTP/1.1 200 Connection established witch means that your client can now make your query throw the TCP Tunnel (TCP datas received will be transmited directly to server and vice versa).【PHP CURL内存泄露的解决方法】相关文章
