You are understanding me correctly; I think there migh be a bug or
feature in how Squid calculates staleness for dateless entities.

It should not be that hard to fix I think. All the logics is there, but
presumabely it gets confused somewhere by not having a date..

The heart of thins is http.c:httpCachableReply(), and this is probably a
good place to start when looking into why the object does not get
cached.

Hmm.. reading the code it even has a comment that such replies are not
cached when received from cache peers... I think you will find it if you
look for it. A possible "fix" is to change the "return 0" to "return 1"
some lines below that. This safeguard probably exists to protect from
misbehaving caches.
