readfile in IE clearing session

[dc_jt]

Ive got the following code which works fine in firefox, however in IE the file opens fine but for some reason it clears my session so once a user has downloaded the file, it logs them out the system.

 

Does anyone know whats causing IE to clear the session?

 

header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($oDoc->document_name));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: private');
    header('Pragma: private');
    header('Content-Length: ' . filesize($sUrl));
    
    ob_clean();
    flush();
    readfile($sUrl);
    exit;

If I had to take a random guess, it would be the Expires line. I would remove that header and see if it makes a difference.

Thanks for the guess, I have tried that already but had no luck! Really dont know why it is doing it in IE. Does anyone have a script which they know definitely keeps the session data in IE??

What version of IE are you testing this on?

 

Just another random guess, have you tried removing the Cache portion as well?

I have just tried it on a few other machines and it looks as though it is a problem with my IE!

 

Thanks for the help anyway.
