Description

I enjoyed reading your recent post on caching. In that post, you remarked that one motivation for caching is to allow third-party libraries to operate on a locally cached file (rather than the abstract file-like interface).

Is there any recommended way to explicitly point to a cached file this with current APIs? I realize it's a bit antithetical to the idea of behind-the-scenes caching, but it would be nonetheless useful for interoperability with other libraries.
