[squid-users] age in the refresh_pattern

[Stand H]

Hi,


                FRESH if expires < now, else STALE
                STALE if age > max
                FRESH if lm-factor < percent, else STALE
                FRESH if age < min
                else STALE

Can someone show how to calculate the age here? Is it age=Now-LM or age=time 
since the object stored in the cache?

Thanks.
