I don't think that's the real reason. The big reason most server
admins hate caches is that they cause the server logs to
under-report traffic levels. Any site that makes money out of
advertising gets paid according to page traffic. If they can do
anything to defeat caches and boost their traffic levels, they will.
It's more money in their pocket.

That bit's easy. I found that blocking port 80 outbound on our router
convinced the most reluctant user that the cache was a good idea :-)

It's not an ego thing, it's real money. In fact I'm surprised more
web admins haven't taken steps to stop their pages being cached.
Bandwidth is cheap if you're making money out of traffic. It's just
another incremental expense which is more than covered by the
incremental revenue it generates.

<soapbox>What's needed (from a web site admin's point-of-view) is a
method to deliver cache information back upstream so that they know
how much traffic they've missed out on, so they can count it. The
admins don't really want the traffic (like everybody else, they only
want just enough bandwidth to deliver their service), but they want
to know about it. But if that's the only alternative, then they'll do
their best to get the traffic because it's worth more to them than it
costs them to get it.</soapbox>

and also looking after Squid)
