If the object expires and cannot be revalidated (no Last-Modified
information) then it won't be revalidated. Squid will then simply try to
fetch a new version, where the fallback on old version mechanism does not
exists.
For the Squid mechanism to be effective you need to include a Last-Modified
header in the reply.
