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

    req = CkHttpRequest_Create();

    //  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:
    CkHttpRequest_putHttpVerb(req,"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:
    CkHttpRequest_SetFromUrl(req,"https://www.chilkatsoft.com/echoPost.asp");

    //  Send form params using application/x-www-form-urlencoded
    CkHttpRequest_putContentType(req,"application/x-www-form-urlencoded");

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

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

    //  The HTTP POST is sent here:
    resp = CkHttpResponse_Create();
    success = CkHttp_HttpSReq(http,domain,port,tls,req,resp);
    if (success == FALSE) {
        printf("%s\n",CkHttp_lastErrorText(http));
        CkHttpRequest_Dispose(req);
        CkHttp_Dispose(http);
        CkHttpResponse_Dispose(resp);
        return;
    }

    //  Display the HTML source of the page returned.
    printf("%s\n",CkHttpResponse_bodyStr(resp));


    CkHttpRequest_Dispose(req);
    CkHttp_Dispose(http);
    CkHttpResponse_Dispose(resp);
