    //  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(L"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(L"https://www.chilkatsoft.com/echoPost.asp");

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

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

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

    //  The HTTP POST is sent here:
    CkHttpResponseW *resp = http.SynchronousRequest(domain,port,tls,req);
    if (http.get_LastMethodSuccess() == false) {
        wprintf(L"%s\n",http.lastErrorText());
        return;
    }

    //  Display the HTML source of the page returned.
    wprintf(L"%s\n",resp->bodyStr());
    }
