Anyone know how to defeat caching - both on the server, and locally on user's browsers? I'm using the following methods in PHP, and HTML, but they don't seem to b working:

------------
PHP:
------------
<?php header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");


------------
HTML:
------------
<META HTTP-EQUIV="Expires" CONTENT="0">



Let me if there's another way or where I'm messing up.

Thanks in advance.

Place the following line in your HTML page:

<meta http-equiv="Pragma" content="no-cache">

Just before the <head> tag. This instructs the browser not to cache the page.

thanx entropy.

Do u know if this works for just defeating caching on the users browser, or also across proxy servers?
