    winsock not recieving data

    i wrote a simple socket client and for testing i tried to connect to a http server and send the http command 'GET / HTTP/1.1' but i get nothing back. i've looked through other post, and searched online, from everything i see it should work. here's the code:
    Code:
    target.sin_family = AF_INET;
    target.sin_addr.s_addr = *((unsigned long *)host->h_addr);
    sck = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (connect(sck, (SOCKADDR *)&target, sizeof(target)) == SOCKET_ERROR)
    {
    	cout << "error connecting to target" << endl;
    	closesocket(sck);
    	WSACleanup();
    	return 0;
    }
    char outBuff[BUF_SIZE];
    char inBuff[BUF_SIZE];
    int bytes_recv;
    do
    {
    	cout << "->";
    	cin.getline(outBuff, BUF_SIZE-2);
    	if (strcmp(outBuff, "quit")==0) break;
    	strcat(outBuff, "\r\n");
    	if (send(sck, outBuff, strlen(outBuff), 0))
    	{
    		cout << "send successful" << endl;
    		bytes_recv = recv(sck, inBuff, BUF_SIZE, 0);
    		if (bytes_recv != 0 && bytes_recv != SOCKET_ERROR)
    		{
    		      cout << inBuff << endl;
    		}
    	}
    	memset(outBuff, 0, BUF_SIZE);
    	memset(inBuff, 0, BUF_SIZE);
    } while (true);
    closesocket(sck);
    WSACleanup();

    Re: winsock not recieving data

    Your HTTP statement is incomplete.
    It should be something like:
    Code:
    char httpreq[] = "GET / HTTP/1.1\r\nHOST:website.com\r\n\r\n";
    Notice the \r\ns
