no cache

which no cache headers do you use ?

 

[RussellReal]

straight from php.net this is what I use and has always been true <3

 

<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>

I've recently seen this:

 

"In order to make Internet Explorer 6 (probably also 7)  not to cache pages you should use only these headers:

header("Cache-Control: no-cache");

header("Expires: -1");

as suggested by Microsoft itself [source: http://support.microsoft.com/kb/234067] "

 

some people do seem to use

    header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");                  // Date in the past 

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

    header('Cache-Control: no-store, no-cache, must-revalidate');    // HTTP/1.1

    header('Cache-Control: pre-check=0, post-check=0, max-age=0');    // HTTP/1.1

    header("Pragma: no-cache");

    header("Expires: 0");
