Neither, please! A short key may be as unique as a long one. For a simple example, consider what a "tiny URL" service does to long URLs. For a complex one, consider various compression encoding schemes that assign just a few bits to commonly found long patterns. In general, if there is a valid use case for something, we should not complain by default. Our cache.log is already full of information-hiding noise. Thank you, Alex.
