Some session data ( I am using php) is written in main window code. There is a link to open a new window and this window will show the previously written session data.  On first click, it works fine. If I close this window, all session data is erased and can no longer be accessed from either main window or popup. I have checked different php settings (trans_sid for ex) and played with settings in cookies section of Konq and tested in Mozilla (works fine)

To illustrate here is test code:

mainwindow.php:
-----------------
<?php
session_start();
$_SESSION['test'] = 'hello';

?>
<a href="popup.php" target="_blank">launch</a>
-----------------

popup.php
---------------
<?php
session_start();

echo $_SESSION['test'];
?>

------------

The "hello" in the popup will only show once. The only solution is to pass the session_id  in url.  Since things work fine on other browser I am assuming this to be a Konq issue.
