in the following script


<?
	session_register("CookiesAktiviert");
	$CookiesAktiviert=1;
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
	<title>Test</title>
</head>

<body>

	<a href='javascript:alert("Hallo Stefan");'>Hallo Stefan</a>

</body>
</html>



the single quotes in the href are replaced by double quotes, if the user does not 
accept cookies. If he accepts the cookie set by the session_register function and
then reloads the file (because the seesion-id has already has been written, this
time the function session_register doesen't try to set a cookie), the single quotes 
are not replaced (which is the desired behaviour).
