in thread OT: Preserving Information

I don't have a problem with a pure cache - one that will check whether information is stale before serving it. But caches that don't check the backend are a gray area. Personally, I don't have a problem with them, as long as they have a reasonable expiration period (that is, if the backend data is removed or modified, the cache should reflect that after a not-to-long period). But if a cache doesn't expire documents that have disappeared, or where the expire period is unreasonably large I think they are wrong. It might have legal problems as well.
