I don't want Browser to cache my web page

dude

I don't want Browser to cache my web page. How can I do that? If the browser do caching my website, it does not show the latest version of my website. How can I make it so that the browser no longer cahches my website. But brings the website new everytime a user comes?

in php

Code:

header("Pragma: no-cache");

in Asp

Code:

<% Response.AddHeader "Pragma", "No-Cache" %>

in html

Code:

IF you need more details on this let me know.

But No-CACHE is generally used on transection related pages.
But for other pages you need to add more info say after 10 days clear cache etc.

If you need more details let me know.

That's a very useful informastion. But somewhere I heard that <META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE"> does not work in some cases. I will ook that up and post here if I find it.

Yes, that's the one I was thinking.

To properly prevent the Web page from appearing in the cache, place another header section at the end of the HTML document. For example:

<HTML>

<HEAD>

<META HTTP-EQUIV="REFRESH" CONTENT="5">
<TITLE> Pragma No-cache </TITLE>

</HEAD>

<BODY>

This is an example of where to place the second header section<br>
so that the "Pragama, No-Cache" metatag will work as it is supposed to.<br>

</BODY>

<HEAD>

<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">

</HEAD>

</HTML>

dude

Thank you both, hasnut and emm. Now I am thinking it may not be a good idea to not allow cache at all. Then even the images will have to be downloaded everytime users come back.

Depends, when it comes to transaction through your shopping cart then some portion you should not cache.
