[squid-users] Refresh pattern issue in squid 3.1.20

[SaRaVanAn]

Hi, All,
I tired suggested refresh pattern, still i was getting TCP_HIT/MEM_HIT.
It's not getting refreshed after 10 minutes.


*Conf*
refresh_pattern -i ^http://[a-z\-\_\.A-Z0-9]+\.wsj\.(net|net|com|edu)/ 10
200% 10 override-expire override-lastmod reload-into-ims ignore-reload

I have gone through the packet captures. It looks like expiry time is
greater than min time of refresh_pattern. But i have used override options.
Here  I am confused whether precedence goes to expiry time or min time .I
am not clear on how it works.

Can you guide me on how it works and why it is not getting refreshed ? I
need experts guidance here


*pushdownAd.css repsonse header timings*
