    // If we know a query param value does not have any special chars requiring URL encoding,
    // just add it.  In this case, there is no need to URL encode "123" because "123" url encoded is still just "123".

    sbValue.append("this is a test")

    // sbUrl contains:  https://www.example.com/something?abc=123&xyz=msg=this%20is%20a%20test
    print("\(sbUrl.getAsString()!)")

    // Send the GET request and get the response body, which is assumed to be text of some sort (HTML, XML, JSON, etc.)
    // (Chilkat automatically decompresses gzipped responses)
