Hello,
I'm a new to squid and triyng to use

Transparent Squid Cache with WCCPv2 on Cisco 7206 router. IOS version is
12.4(1). Squid cache and clients are in a same subnet.

I have a problem the client browser the page cannot display error message.
And also from squid cache there aren't any log in the access.log and
store.log.
What should i do? please help me.

I hope and waiting for your reply,

Following are my configurations:
