Maybe yes, maybe no.

HTTP has gone long way past the point where 1 URL meant 1 object. These
days there can be up to millions of different Vary: versions of
object(s) for each URL. Or maybe Squid had it cached, but was unable to
use the cached version for some other reason. These are also why ICP
which only tests the URL can be HIT and an actual fetch can be a MISS.

Are you able to supply the URL, or at least the entire (unedited) reply
headers reported by squidclient?
