Okay. It sounds like you are the authoritative for that website.

What you seem to be attempting is to replicate the behavior of:
   Cache-Control: maxage=0, s-maxage=60, max-stale=60
which permits middle caches to store a copy for up to 60 seconds from
original generation time and makes end clients to always request fresh ones.

BTW, What version of Squid?
