title: sending a POST request with Google's C++ native client
body: <p>Can someone give an example of how to send a POST request with Google's C++ native client? The question has been <a href="https://stackoverflow.com/questions/6935585/http-post-request-with-googles-c-native-client">asked before</a>, but Google's documentation is not very helpful (and in some cases non-existent). And yes, I have been scouring github for help, but to no avail. </p>
