Sorry - I can't confirm that, I don't know the internals well enough
for that.

I am still interested in getting this patch to be either included or
tested however. If I can help on testing this please let me know.

I have compiled a version with the patch on squid 3.4.5 and it appears
to do what we want, however it seems to have a bug. When a stale object
needs updating, it does query the sibling, and if it has a fresher copy
it is returned. If however the sibling does not have a fresher copy the
original squid queries the origin, but seems to keep the "Age:" header
from the last stale request, so although it has updated the object it
will expire quicker than it should as it has an incorrectly calculated
"Age:" header on it. I assume this is due to the patch introducing
something new that is not being considered when refreshing from a
sibling. Anyone interested in helping on this ?

Many thanks
Michael
