hello, my site, zorpia.com, is a pretty popular site. we get more than a million pageviews per day. and we are trying to use squid server to serve only navigation images like the tab images or buttons. i don't think anybody will abuse our navigation images. i think the hits are caused by the huge amount of users we have. is our situation normal to you considering there are no abuse?
