[squid-users] forwarding loop using squidguard

Hi all.
I'm trying to use squidguard to strip out jsessionid field from some
URLs. I've configured squidguard to strip the part of a URL containing
;jsessionid=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.tomcat1
The problem is that when squid passes an URL containing this field to
squidguard it generate a warning of forwarding loop and shows an error
page access denied depending (i think) on error 111 connection refused.
Please help me....thanks a lot,Matteo Villari

That is my squid.conf file
