Filename conventions are irrelevant in HTTP. In order for your application
to work correctly, it must obey the same constraints as any cache.
That means the client must map URLs to responses, not filenames.
How the application stores things locally is application-dependent, but
there are sufficient clues given by Content-Location and Vary such
that it can indeed know whether or not negotiation was used.
