Sebastian, try this:
It can be accomplished with JavaScript or a meta refresh tag...
just do a
<meta http-equiv="Refresh"
content="3600;URL=expiredNotice.php">
the 3600 is the number of seconds to expire the page and
expiredNotice.php is the page the user will be sent to.
or search on google.com for "make page expire" for many other options.
