If there is a newer file available on the server, we definitely want to download it. If, however, there wasn’t a new file on the server, we’ll bring back a 304 header, no new file, but an entire roundtrip of latency. We can completely cut out the overhead of a roundtrip of latency. What do we mean by a mutable or immutable file?
