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.
