How to check Server Response?

Hi,

I am connecting funambol server(Http Session).
I want to add some contacts to funambol server(To Synchronize Contact with Client).

I m sending data through below mention API.

HttpSendRequest(hInternet, headers, wcslen(headers), szHeader,wcslen(szHeader));
szHeader = "Data contains"

I am checking the response using InternetReadFile( hInternet, buffer, 10000, &dwRead )

Reading buffer data? Is this a wrong way?
If yes then : How to check the response?
Please reply me if information is not sufficient.

Thanks in Advance.
