Transparent Proxy Setup

I have been playing around with a transparent proxy server the last 2 days..
Really easy to set up
Redhat 6.1 fresh install
clean squid 2.3 Stable 1 install
2 network cards
192.168.0.1
202.49.244.X

echo 1 > /proc/sys/net/ipv4/ip_forward
ipfwadm -I -a accept -W
ipfwadm -I -a accept -P tcp -D 192.168.0.254 80
ipfwadm -I -a accept -P tcp -D 202.49.244.X 80
ipfwadm -I -a accept -P tcp -D 0/0 80 -r 3128

+ on working caching server setup.

httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

And set up default gateway of dialup server (max4000) to 192.168.0.254
It works brilliantly except.

Goto a page.. view on web browser..
goto page again (I know the page has changed in some manner)
click on reload.. doesn't refresh. (same page again)
alt-reload page .. doesn't refresh (same page again)
ctrl-reload page.. doesn't refresh (same page again)

I can't get the new page..

Is this one of the limitations of a transparent proxy server??
Has anyone found out a way around this?
(it works properly if I manually set up the proxy server in explorer)

I know of a few ISP's in New Zealand using similar methods
(family-nice ISP who filter out all the porn, using a VERY expenise hardware
proxy/filter system)

Thanks
