void ChilkatSample(void)
    {
    bool success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkHttpRequest req;
    CkHttp http;

    // If any custom headers need to be included with the POST, add them
    // by calling SetRequestHeader

    // Note: An application should never explicitly set the Content-Length header.
    // The Content-Length is automatically computed and added by Chilkat.

    // Here are some examples of custom headers.  

    // Perhaps your particular app needs some sort of custom-computed Authorization header...
    http.SetRequestHeader("Authorization","my-custom-computed-auth-value");

    // Another custom header for some hypothetical app:
    http.SetRequestHeader("X-Pass-Timestamp","my-custom-computed-timestamp-value");

    // The following "Accept" header may be set, but it really isn't necessary:
    http.SetRequestHeader("Accept","application/json");

    const char *jsonText = "{ some JSON text ... }";

    // To use SSL/TLS, simply use "https://" in the URL.

    CkHttpResponse resp;
    success = http.HttpStr("POST","http://www.someserver.com/someJsonEndpoint",jsonText,"utf-8","application/json",resp);
    if (success == false) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    // Display the JSON response.
    std::cout << resp.bodyStr() << "\r\n";
    }
