At other call sites we use url.isLocalFile() rather than url.protocolIs("file"). I think we should do that here.

Comment is unclear because “adjustMIMETypeIfNecessary” does not seem to be the same thing as “MIME type sniffing”. Maybe we should rename something or change the comment a bit?

Is 304 the *only* response where we don’t want to do sniffing? If so, why is it just that one?
