[squid-users] false TCP_REFRESH_HIT for cached objects

Hello,

I've squid 2.6 config as Transparent reverse-proxy server. For some
urls squid is not using the cached object, instead it keep sending
request to FIRST_UP_PARENT/200. Infact most of hits on squid are using
this status code, very few have status code TCP_MEM_HIT/200. I believe
the cached objects are stale. But how to remove this object from
cache, Or there is some other problem. Log lines from access.log
