[squid-users] Refresh pattern issue in squid 3.1.20

[SaRaVanAn]

Hi,
We are using squid 3.1.20 in our box. We are facing issues on configuring
and validating the refresh patterns. It looks like squid is not honoring
the refresh patterns properly.


*configuration*
*refresh_pattern -i ^http://.wsj./.* 10 200% 10 override-expire
override-lastmod reload-into-ims ignore-reload*
refresh_pattern -i \.(gif|png|jpg|jpeg|ico)$ 480 100% 480 override-expire
override-lastmod reload-into-ims
refresh_pattern -i \.(htm|html|js|css)$ 480 100% 480 override-expire
override-lastmod reload-into-ims

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


As per above refresh pattern squid should refresh the cache every ten
minutes for "*^http://.wsj./.*" .  *But I am always getting either
TCP_HIT/TCP_MEM_HIT even after hours. Why is it so? . Please find the logs
below
