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;

    // This example simulates this FORM:
    // <form action="echoPost.asp" method="post">
    // First name: <input type="text" name="firstName"><br />
    // Last name: <input type="text" name="lastName"><br />
    // <input type="submit" value="Submit">
    // </form>
    // The online FORM is found at this URL:
    // https://www.chilkatsoft.com/simpleForm.html

    // Build an HTTP POST Request:
    req.put_HttpVerb("POST");

    // The FORM target is http://www.chilkatsoft.com/processPost.asp
    // An easy way of filling out most of the HTTP request object
    // is to call SetFromUrl:
    req.SetFromUrl("https://www.chilkatsoft.com/echoPost.asp");

    // Send form params using application/x-www-form-urlencoded
    req.put_ContentType("application/x-www-form-urlencoded");

    // The only remaining task is to add the params to the 
    // HTTP request object:
    req.AddParam("firstName","Matt");
    req.AddParam("lastName","Jones");

    // Send the HTTP POST and get the response.
    // The POST is being sent to chilkatsoft.com, on port 443 (using TLS)
    const char *domain = "chilkatsoft.com";
    int port = 443;
    bool tls = true;

    // The HTTP POST is sent here:
    CkHttpResponse resp;
    success = http.HttpSReq(domain,port,tls,req,resp);
    if (success == false) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    // Display the HTML source of the page returned.
    std::cout << resp.bodyStr() << "\r\n";
    }
