Much more effective is to provide proxies way to tell server which version
of page do they have and check if it's still fresh.

Learn how the If-Modified-Since and Etag: headers work. And of course the
Cache-Control...

I think the only case where you really need page that is not cached is where
you put the current timestamp into the (x)html instead of using e.g.
javascript.
