Thank you Amos,

We have tried by enabling "server_http11 on" in squid.conf but no
luck. In the access log for we can see lot of TCP_MISS/000.
In the iptables we have used the following rule "/sbin/iptables -t nat
-A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3128"
Can you suggest how to check traffic other than port 80 is pushed
through squid and make only port 80 to pass through?

Thanks.
