Try this :

********* BEGIN script.php **********
<?php
session_cache_limiter('private');
session_start();
?>

<html>
<body>
<form method="post" action="script.php" enctype="multipart/form-data">
<input type="submit" name="sub" value="submit">
<input type="file" name="any" size="50">
</form>
<br>
</body>
</html>
************** END ************

Now, just click "sumbit" a couple times and try to use yor
browser "Back" button. The page will expire.

To solve this, just change the following line :
   <input type="file" name="any" size="50">
to :
   <input type="file" name="" size="50">

Remember that when calling this script again you must change the way you called it at the first time, i.e., 
http://server.com/script.php?something .

So, click "submit" a few times again and click "Back". 
At this time the page won't expire.

I tryed this with IE 6.0 / Windows XP and IE 5.5 / Windows 98.
Thanks for your support !

I've got the same error with the latest CVS version.

It's a little bit crazy, but if you change the name using
javascript,

/*
<input type="file" name="" size="50" onfocus="this.name='any'">
*/

the page won't expire. 

Any ideas ?

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Sorry, I accidently selected wrong solution..this is not any bug. So please ask on some support forum how to deal with this.
