ex.

Only Konqueror does not contained this "bug" :
- IE7
- Safari
- Firefox 
load twice url.

It can make many errors in case of Apache2/PHP server whith BDD "insert" (2 insertions with this reload).

The logs of apache2 server (all os) show that the navigator get the page two times.

Sorry for my bad english (i'm french)

Exemple of PHP script (index.php):
--------------------------------------
<?php
session_start();
if (isset($_SESSION["nb"])){
    $_SESSION["nb"]++;
}
else{
    $_SESSION["nb"]=0;
}

?>
<html>
<head><title>Bug test</title></head>
<body>
<a href="index.php?var1=xxx">click me</a>
<?php echo "<h1>Load : ".$_SESSION["nb"]."</h1>"; ?>
<img src="" />
</body>
</html>
