A stale if error will just serve the stale version. The mustr validate response directive indicates that the response can be stored in the cashes and can be used while fresh. There's other ones here, private that will a say that this asset can only be cashed on a private cash. And i like to think of it as an java script where if you have like style dot c s s,. you pop an immutable tag on there, and what that will the browser is cash this thing essentially forever.

In this Hasty Treat, Scott and Wes answer a question about caching, cache control headers, an explanation of the fields for caching.
