Are you using the offline mode of squid? If so, then any no-cache from
the client is ignored, as well as expiry times on objects..

Other configuration options which could affect this is if your are using
any of the reload-into-ims options (or ignore-reload)

My test system seems to honor client sent no-cache quite nicely even if
the origin site cannot be reached. I am not using any of these tweaking

Are you sending your HEAD request directly to Squid, or thru this Apache
proxy first?
