[squid-users] Refresh pattern issue in squid 3.1.20

[SaRaVanAn]

Thanks for prompt response.

I want to match all the URL's which has a pattern of "wsj" (example: *.
wsj.com, *.wsj.net, *.wsj.edu ) . Does wildcard makes sense in squid
refresh pattern? Can we have something like this?

 refresh_pattern -i ^http://*\.wsj\.*/ 10 200% 10 \
    override-expire reload-into-ims
