    ; 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 = CkHttpResponse::ckCreate()
    If resp.i = 0
        Debug "Failed to create object."
        ProcedureReturn
    EndIf
