Simply disable caching:
<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
session_start();
if (!session_register("var")) {
session_register("var");
$_SESSION["var"] = 1;
} else {
$_SESSION["var"]++;
}
echo $_SESSION["var"];
?>
This will output 1 on first load,
Go to some other site, then hit back, and it will output 2 :)
