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?
