feature request cache refresh

[Henry Paulissen]

As far as I know, varnish does this by default?

To expire content you have to serve proper expire and last-modified headers.
Some (dynamic) applications sets inproper or even non of those headers at
all.

a parameter to vary the behaviour of 'grace', or to have an additional 
parameter for "max age of stale content to serve".
