Okay, so you're looking for a session module rather than a cache. Apache::Session doesn't handle expiration, but you could add it, as many here have. You could also just use one of the general-purpose storage modules like MLDBM::Sync, BerkeleyDB, or the storage modules in Cache::Cache (like Cache::FileBackend) and then add expiration. Those are all generic storage modules with no cache-specific stuff in their APIs. - Perrin
