Serving stale items from cache

[stonor]

I would love to see this too in Nginx.

The pattern is described here: http://www.mnot.net/blog/2007/12/12/stale


The only software I've seen this implemented in is Squid 2.7
(stale-while-revalidate).

>From time to time I see backends taking 800ms+  to generate a page at
low traffic. It would be nice to hide most of these requests to the end
user.
