squid cache missing TCP

[mister]

i have configured squid configuration file to cache the websites using these commands

httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

and i have reconfigured my ip tables by these commands

iptables --flush
/etc/init.d/iptables stop

iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT

iptables -A INPUT -i lo -j ACCEPT
iptables -A OUTPUT -o lo -j ACCEPT

iptables -A INPUT -i eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT

iptables --append FORWARD --in-interface eth0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

iptables -A INPUT -i eth0 -j ACCEPT
iptables -A OUTPUT -o eth0 -j ACCEPT

iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to 192.168.3.1:8080

iptables -A INPUT -j LOG
iptables -A INPUT -j DROP

echo 1 > /proc/sys/net/ipv4/ip_forward
/etc/init.d/iptables save
/etc/init.d/iptables start

and the squid is working because the access.log file record every thing i searched but the problem that in every line of access.log i get this error
....TCP=miss....

and i have tried many things but i still losing TCP so can anybody help me!??

I dont understand what you mean by 'losing TCP'.

I could be wrong here, but doesn't 'miss' in this context mean that the file requested wasn't in the proxy cache, so squid had to go out to the real internet for it?

yeah sure, but even if i search any page for multiple times im always getting the TCP_miss for every sites i have searched >>?
