That logic says STALE (!<min ... choosing else). IMHO, Max is there because max-age (given by server) CAN be less than min (configured). > And how does the Percent option exactly works? Ok, an object without ANY other min/max/expires has an age since created the server told squid (via Last-Modified: header). The time between LM and when squid last received a clean copy is 100%, now ADD X% to the age and that is the new max, 0% is the new min. Amos
