Hi Sam,
 
I have not refused to add the codes, in fact I had already did, and also I do not disagree that Web Caching adds efficiency. Problem is, what the use of adding the code, if the pages with the code are inaccessible. My browser still downloads the old pages - without the code

Sir,
Web caching is a reality lets accept this fact from the technical point of view, there is not single major provider in the world who does not practice web caching. Best Practice is a standard that has to be adopted by all techies to try & reach 100 % efficiency ... any sane techie on the list would definitely agree with me that the 100 % mark cant be reached but how do we ensure we get nearer to that level as we ran this race ? By refusing to add those codes you are refusing to add efficiency to your website or your companies website .. there is no loss in implementing best practices regardless of where you source the information from, there is a big loss by refusing to add a best practice on your fingertips while basing your from a not very professional view. You need to ask yourself this ?

Do I need a win win situation,  or a win loss , or loss loss its only 3 options you hv pls take the win win since there is no loss win .. trust me you want your website efficient and the company  want's that too its not something to do with your wants from a personal point of view its "NEED" on technical level.

1. How many providers have caching implemented on their network's globally  ?

2. How does that affect my websites efficiency ?

3. What should I do to ensure those who hv caching implemented & those who dont hv caching still get up to date information ?

4. Can I tell the world to stop web caching ?

The document at http://en.wikipedia.org/wiki/Web_cache & many more like this was not something designed by your provider but a panel of People who make the internet a better experience, by humbly taking good Ideas and turning them into best practices. You hv a choice to become one of them right now or frustrate their efforts in this race.

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 
%>
