    ;  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::setCkHttpVerb(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::ckSetFromUrl(req,"https://www.chilkatsoft.com/echoPost.asp")

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

    ;  The only remaining task is to add the params to the
    ;  HTTP request object:
    CkHttpRequest::ckAddParam(req,"firstName","Matt")
    CkHttpRequest::ckAddParam(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.s = "chilkatsoft.com"
    port.i = 443
    tls.i = 1

    ;  The HTTP POST is sent here:
    resp.i = CkHttp::ckSynchronousRequest(http,domain,port,tls,req)
    If CkHttp::ckLastMethodSuccess(http) = 0
        Debug CkHttp::ckLastErrorText(http)
        CkHttpRequest::ckDispose(req)
        CkHttp::ckDispose(http)
        ProcedureReturn
    EndIf

    ;  Display the HTML source of the page returned.
    Debug CkHttpResponse::ckBodyStr(resp)


    CkHttpRequest::ckDispose(req)
    CkHttp::ckDispose(http)
