    {
    CkString strOut;

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

    CkHttpRequest req;
    CkHttp http;

    // The PUT request to be sent will look like this:

    // PUT /request HTTP/1.1
    // Content-Type: application/jsonrequest
    // Cookie: JSESSIONID=1234
    // Content-Encoding: identity
    // Host: json.penzance.org
    // Accept: application/jsonrequest
    // Accept-Encoding:
    // Content-Length: 72
    // 
    // {"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("");
    http.put_UserAgent("");
    http.put_AcceptLanguage("");

    // Suppress the Accept-Encoding header by disallowing 
    // a gzip response:
    http.put_AllowGzip(false);

    // If a Cookie needs to be added...
    http.SetRequestHeader("Cookie","JSESSIONID=1234");

    // Add the Content-Encoding: identity header.
    http.SetRequestHeader("Content-Encoding","identity");

    // Modify the default "Accept" header:
    http.put_Accept("application/jsonrequest");

    const char *jsonText = "{\"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.

    const char *responseBody = http.putText("http://json.penzance.org/request",jsonText,"utf-8","application/jsonrequest",false,false);
    if (http.get_LastMethodSuccess() != true) {
        strOut.append(http.lastErrorText());
        strOut.append("\r\n");
    }
    else {
        // Display the JSON response.
        strOut.append(responseBody);
        strOut.append("\r\n");

    }
