For objects with no expiry and no Last-Modified min is used. If there is a known Last-Modified then % of the modification age bounded by max is used. There is also a refresh_pattern option to make min apply when there is a last-modified as well. Generally setting min > 0 in normal Internet proxies is not a good idea, and may cause cache problems with many sites still. Not technically forbidden by HTTP specifications, but unexpected by many webauthors. Regards Henrik
