There is a threshold set in squid.conf limiting caching of objects which
can not be revalidated (no cache validator in the response header) and
which expires quickly.

minimum_expiry_time or something like that.

Fixing the server to provide and support cache validators is the better
option however.

A cache validator is Last-Modified or ETag, and is used by
If-Modified-Since or If-None-Match request headers to validate the
freshness of the cached copy.
