webserver and read the content data

Thanks,

    I will describe my code snippet below

    The module for connecting to server

         SOCKET RequestSock;
         SOCKADDR_IN ClientAddr;
         RequestSock =
WSASocket(AF_INET,SOCK_STREAM,0,NULL,0,WSA_FLAG_OVERLAPPED);

I don't know much about 'OVERLAPPED' in Windows, but I think
it's something like 'nonblocking' in Unix.

         pHost = gethostbyname(pcTargetURL);
         memset(&ClientAddr,0,sizeof(ClientAddr));
         int iAddrLen = sizeof(ClientAddr);
         ClientAddr.sin_family = AF_INET;
         memcpy(&ClientAddr.sin_addr,pHost->h_addr, pHost->h_length);
         ClientAddr.sin_port = htons(atoi(pcPort));
         if(0 != connect(RequestSock,(SOCKADDR *)&ClientAddr,
sizeof(SOCKADDR_IN)))
         {
              closesocket(RequestSock); // Connection failed
              return false;
         }

         WSAOVERLAPPED SendOverlapped;
         DWORD dwSendDataLen = 0;
         WSABUF ClientRequestBuf;
         WSAEVENT SendEvent[1];
         ClientRequestBuf.buf = pcData;
         ClientRequestBuf.len = strlen(pcData);
         SendEvent[0] = WSACreateEvent();
         SendOverlapped.hEvent = SendEvent[0];
         iRes =
WSASend(RequestSock,&ClientRequestBuf,1,&dwSendDataLen,dwFlag,
&SendOverlapped,NULL);
            // Sending data to the server

At this point, the send probably hasn't actually happened.
And if you call [WSA]Recv and it returns, it almost certainly
hasn't actually been done either. You probably have to do
some kind of synchronization with the .hEvent, following
whatever Windows rules are applicable.

    FYI
        pcPort = 443
        pcTargetURL = L"www.facebook.com";
       pcData = "GET https://www.facebook.com HTTP/1.0\r\n\r\n"
