Many thanks Amos, I've just tried this and it does indeed query
sibling
for stale content as we want.
I think there is some logic that will need updating however in
HttpHeader.cc possibly, as when an object becomes stale and the
sibling
does not have a fresh copy, the origin is queried but the "Age:"
and
"X-Cache:HIT from" headers are still on the new request, even
though it
was a fresh check from the origin. I think these headers need to be
deleted/updated.
Is this a fully new set of headers+object from the server?
or a revalidation update/refresh from the server?
It's a revalidation, so it sends an "if-modified-since" to the origin
which replies with a "304 not modified". At this point it seems the Age:
needs recalculating.
Thanks
Michael
