The code you gave for preventing the message appearing with the back button did not work for IE7,
but changing the line:
$offset = 60 * 60 * 24 * -1;
to
$offset = 60 * 60 * 24 * 1;
makes it work OK, with my set up there's no issues with serving cached versions of the page.
<?php
// Original code found at http://www.mnot.net/cache_docs/
// thanks to hervard at gmail dot com for this solution to browser back button problems
header("Cache-Control: must-revalidate");
$offset = 60 * 60 * 24 * 1;
$ExpStr = "Expires: " . gmdate("D, d M Y H:i:s", time() + $offset) . "
GMT";
header($ExpStr);
?>
I've tested this in a standalone version of IE6
Also tested in IE7, Firefox 1.5, Opera 7.54
