Now, how are you going to be able to avoid the systems and browsers cache, you
think? The whole idea of presenting a webpage (and all that is in there) is that
you serve it out to a client. The client takes care of the rendering. To be able
to do that, it needs to cache what ever you serve out.
Or what about a local copy on a proxy server? Besides, one is likely to be
allowed to have a copy for personal use (not for distribution). Moreover, any
clever visitor _will_ get his/her hands on a local copy of your content, if s/he
wishes to have one. No matter how well you protect your stuff.

So, either don't publish. Or publish, possibly put a copy right notice on you
pages, and accept that the whole construct of publishing on the world wide web
involves both servers and client to do their bit.
