This is a GET url, rather than a POST.  Browsers and firewalls
are free to cache GET urls, since they are guaranteed not to 
change anything on the server; only POST urls are supposed 
to do that.

Generate a unique number - epoch seconds is fine - when you 
serve up each page and attach it to the end of each URL
( http://www.yoursite.com/index.html/998778423 )
and you will *always* get a fresh page because the URL has
never been seen before by the cache.
