There's a difference between putting the cache-control
information in HTML META tags, and putting it in HTTP
headers. Intermediate proxies are required to read the
HTTP headers, but will probably not read the HTML META
tags. Here's a good article:
http://www.mnot.net/cache_docs/
Note that rfc2616 (the HTTP spec) in section 13.13
indicates that there is a difference between a web
browser's cache and a web-browser's history list.
So it's possible that a browser will ignore cache
busting headers when you're navigating around with
the forward/back buttons. (Mozilla, for example,
will allow the back button to access 'max-age=0'
pages, but revalidates pages with 'no-store'.)
