    // This example duplicates the HTTP POST shown at
    // http://json.org/JSONRequest.html

    // Specifically, the request to be sent looks like this:

    // POST /request HTTP/1.1
    // Accept: application/jsonrequest
    // Content-Encoding: identity
    // Content-Length: 72
    // Content-Type: application/jsonrequest
    // Host: json.penzance.org
    // 
    // {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

    // First, remove default header fields that would be automatically
    // sent.  (These headers are harmless, and shouldn't need to 
    // be suppressed, but just in case...)
    http.put_AcceptCharset(L"");
    http.put_UserAgent(L"");
    http.put_AcceptLanguage(L"");
    // Suppress the Accept-Encoding header by disallowing 
    // a gzip response:
    http.put_AllowGzip(false);

    // If a Cookie needs to be added, it may be added by calling
    // AddQuickHeader:
    success = http.AddQuickHeader(L"Cookie",L"JSESSIONID=1234");

    const wchar_t *jsonText = L"{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}";

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

    // IMPORTANT: Make sure to change the URL, JSON text,
    // and other data items to your own values.  The URL used
    // in this example will not actually work.

    CkHttpResponseW *resp = 0;
    resp = http.PostJson(L"http://json.penzance.org/request",jsonText);
    if (http.get_LastMethodSuccess() != true) {
        wprintf(L"%s\n",http.lastErrorText());
    }
    else {
        // Display the JSON response.
        wprintf(L"%s\n",resp->bodyStr());
        delete resp;
    }
