I was jst about to say what Anangwe recommends because web caching is a reality on the internet, you cant jst do away with web caching not even where technology has been first developed. In the market there are all sorts of appliances from Cisco to Juniper that are built to cache traffic besides Web caching. The big question should be , when will web developers conform to best practice ? Most developers mind about design of the web site but forget to add to cart best practices.

if its a php page you can use.

You can use the pragma :nocache header in your script code
to force out any cache instances.

---------------------------------------------
Before you output any HTML data put this in your script

Header("Cache-control: private, no-cache");
Header("Expires: Mon, 26 Jun 1997 05:00:00 GMT");
Header("Pragma: no-cache");

---------------------------------------------

Additional to that you can add

header ("Last-Modified: " . gmdate ("D, d M Y H:i:s") . " GMT");

and following html-Tag

<META http-equiv="expires" content="0">

if its an asp page you can add

<%
pStr = "private, no-cache, must-revalidate"
Response.ExpiresAbsolute = #2000-01-01#
Response.AddHeader "pragma", "no-cache"
Response.AddHeader "cache-control", pStr
%>
