squid refresh_pattern

squid.conf에 이런게 있어서 무슨 의미인가 보는 중

refresh_pattern ^ftp:           1440    20%     10080 refresh_pattern ^gopher:        1440    0%      1440 refresh_pattern -i (/cgi-bin/|\?) 0     0%      0 refresh_pattern .               0       20%     4320

봐도 모르겠다!!!!

usage: refresh_pattern [-i] regex min percent max [options] By default, regular expressions are CASE-SENSITIVE.  To make them case-insensitive, use the -i option. 'Min' is the time (in minutes) an object without an explicit expiry time should be considered fresh. The recommended value is 0, any higher values may cause dynamic applications to be erroneously cached unless the application designer has taken the appropriate actions. 'Percent' is a percentage of the objects age (time since last modification age) an object without explicit expiry time will be considered fresh. 'Max' is an upper limit on how long objects without an explicit expiry time will be considered fresh. The value is also used to form Cache-Control: max-age header for a request sent from Squid to origin/parent. options: override-expire override-lastmod reload-into-ims ignore-reload ignore-no-store ignore-private max-stale=NN refresh-ims store-stale

기본적인 걸 캐싱하지 않도록 되어 있는데 이걸 60분으로 바꾸니 먼가 되긴 하는 듯?
