[Feature Request] Stale-white-revalidate

[modbender]

Is it possible have a mechanism like stale-while-revalidate?
Basically what I mean is, the response with unique key will be cached until a timeout, and after timeout, the fresh data will be fetched in background (non blocking) and until this fresh data is fetched, cached data will be served.

If this is possible, TTFB could be reduced by atleast 80%.
