Refresh *rate*? AFAIK we have no such concept in Squid. It sounds like
some metric the log analysers generate.

Squid will refresh anything that needs refreshing at the point when the
client needs fresh data.

   If the client requests no-cache the cached object will be ignored and
a new one fetched.
   If earlier replies specified no-store or private there may be nothing
cached to be refreshed and a new one fetched.
   If the cached reply has an Expires header it will be refreshed at
next use following that exact timestamp.
   If the client requests max-age=60 Squid will refresh the reply at 61
seconds old or more.
   As a final backup a refresh_pattern supplies parameters to a
freshness estimation algorithm that will be applied.
