While I agree that, assuming the cache has enough knowledge to know
the scope of validity of a 304 response, that would be a better
solution, in the context of a small corporate cache, I can revalidate
entries which were TCP-MISS/304's by scanning the logs and
occasionally running a batch job to refetch them, so having IMS
satisfied from cache would allow me to do this with much less disk
overhead and would probably be a necessary step in a full IMS
strategy, anyway.
