    {
    BOOL success;

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

    req = CkHttpRequestW_Create();
    http = CkHttpW_Create();

    // 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...
    CkHttpW_SetRequestHeader(http,L"Authorization",L"my-custom-computed-auth-value");

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

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

    jsonText = L"{ some JSON text ... }";

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

    resp = CkHttpResponseW_Create();
    success = CkHttpW_HttpStr(http,L"POST",L"http://www.someserver.com/someJsonEndpoint",jsonText,L"utf-8",L"application/json",resp);

        CkHttpW_Dispose(http);
        CkHttpResponseW_Dispose(resp);

    }

    // Display the JSON response.
    wprintf(L"%s\n",CkHttpResponseW_bodyStr(resp));


    CkHttpRequestW_Dispose(req);
    CkHttpW_Dispose(http);
    CkHttpResponseW_Dispose(resp);
