func chilkatTest() {
    var success: Bool = false

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

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

    // If any custom headers need to be included with the POST, add them
    // by calling SetRequestHeader

    // Note: An application should never explicitly set the Content-Length header.
    // The Content-Length is automatically computed and added by Chilkat.

    // Here are some examples of custom headers.  

    // Perhaps your particular app needs some sort of custom-computed Authorization header...
    http.setRequestHeader("Authorization", value: "my-custom-computed-auth-value")

    // Another custom header for some hypothetical app:
    http.setRequestHeader("X-Pass-Timestamp", value: "my-custom-computed-timestamp-value")

    // The following "Accept" header may be set, but it really isn't necessary:
    http.setRequestHeader("Accept", value: "application/json")

    var jsonText: String? = "{ some JSON text ... }"

    // To use SSL/TLS, simply use "https://" in the URL.

    let resp = CkoHttpResponse()!
    success = http.httpStr("POST", url: "http://www.someserver.com/someJsonEndpoint", bodyStr: jsonText, charset: "utf-8", contentType: "application/json", response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    // Display the JSON response.
    print("\(resp.bodyStr!)")
