Hi Poul,
Any work around possible in varnish to make varnish check objects at backend
some time before they actually reach their expires time? Or is it just not
possible to do so in varnish?
Thank you.

Prefetch never got implemented, we found other ideas to solve the problem,
such as grace mode.

Is obj.grace now changed to beresp.grace for the code in varnish
