Hi, I would like to know what is the unit of min and max in refresh_pattern? I have override the expire and lastmod header so that i can cache non-cachable content. but doing this causes the server keeping old cache even though the server has made the modification. my current setting is like this
refresh_pattern . 1440 33% 4480 override-expire override-lastmod ignore-reload I want to set it so that anything not older then half a day should be considered fresh, otherwise, go get another copy. is 1440 count as min here?
