Page caching just saves files to disk (with the assumption that the
web server serves these without touching rails). This just doesn''t
support time base expiry on its own - there is no code that gets run
when serving such a file to check whether the cache is still valid
(although you could of course have some external bit of code that
deletes old files from the cache directory).
caches_action should work though, assuming that the underlying cache
store used by action caching supports expiry (I don''t believe file
store does).
