Please enable log_mime_hdrs and then show the request history of the
URL in question, and your refresh_pattern settings.

log_mime_hdrs allows us to see what is going on, but to gain an
understanding some history of the object is needed

  1) A initial TCP_MISS/TCP_REFRESH_MISS where the object got cached
  2) Maybe some TCP_HIT [remove duplicates if there is many]
  2) The next TCP_MISS/TCP_REFRESH_MISS where you think the object
should have been a HIT..

This can then be applied to rules about cachable request and your
refresh_patterns to verify if the object should really have been a
hit, or if there is a valid reason to why it was processed as a cache
miss.
