proxy store question

[Fabio Coatti]

Hi all, I'm looking at proxy store directive, that would be really useful for 
a situation that we are facing, but I'm wandering how the store is 
invalidated: when a new page is requested to the backend instead of serving 
the cached one?
Is possible to set a timeout, so if nginx finds that the stored page is older 
than a fixed amount of time it fetches again the page, otherwise it serves 
the one in the store, regardless of any header?

Thanks for any answer.
