Then, yes, we speak about the 'classical' browser cache (even if a file is in
the appcache of the _current_ application, it should return that it's cached
too because it won't be loaded over the network).

I would also expect the appcache of other apps to be used in a 'conditional'
way. If 'http://syn.org/all.json' is appcached by 'syn.org' then the browser
should issue an HTTP HEAD If-Modified-Since request to see if it's still
up-to-date and call back whether the data is still valid or not.

The goal of this API is really to work over NETWORK resources to know if you
can use them without triggering their download.
