func chilkatTest() {
    var success: Bool = false

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

    let req = CkoHttpRequest()!
    let http = CkoHttp()!

    // The PUT request to be sent will look like this:

    // PUT /request HTTP/1.1
    // Content-Type: application/jsonrequest
    // Cookie: JSESSIONID=1234
    // Content-Encoding: identity
    // Host: json.penzance.org
    // Accept: application/jsonrequest
    // Accept-Encoding:
    // Content-Length: 72
    // 
    // {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

    // First, remove default header fields that would be automatically
    // sent.  (These headers are harmless, and shouldn't need to 
    // be suppressed, but just in case...)
    http.acceptCharset = ""
    http.userAgent = ""
    http.acceptLanguage = ""

    // Suppress the Accept-Encoding header by disallowing 
    // a gzip response:
    http.allowGzip = false

    // If a Cookie needs to be added...
    http.setRequestHeader("Cookie", value: "JSESSIONID=1234")

    // Add the Content-Encoding: identity header.
    http.setRequestHeader("Content-Encoding", value: "identity")

    // Modify the default "Accept" header:
    http.accept = "application/jsonrequest"

    var jsonText: String? = "{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}"

    // IMPORTANT: Make sure to change the URL, JSON text,
    // and other data items to your own values.  The URL used
    // in this example will not actually work.

    let resp = CkoHttpResponse()!
    success = http.httpStr("PUT", url: "http://json.penzance.org/request", bodyStr: jsonText, charset: "utf-8", contentType: "application/jsonrequest", response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    print("Response status code: \(resp.statusCode.intValue)")
    print("Response JSON:")
    print("\(resp.bodyStr!)")
