note 82597 added to function.readfile

I'm having an issue with browers except FireFox 2. I'm trying to use my download script to download from external URLs. Firefox handles it fine and downloads the file but Internet Explorer 7 and Safari 2 only download a placeholder (empty) file. Any ideas why I can't handle the external URLs? I can swear it was working fine before but then out of no where a user emailed me saying it wasn't working anymore. This is my code (with a bunch of headers added from posts here): # Set Format Type if ($audioformat == "wma") { header('Content-type: audio/x-ms-wma'); } else if ($audioformat == "mp3") { header('Content-type: audio/mpeg'); } $fullpath = $audiopath .$artist. '/' .$filename; # header info for download header('Content-Length: ' . filesize($fullpath)); header('Content-Disposition: attachment; filename="' . $filename. '"'); header('Content-Transfer-Encoding: binary'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Expires: 0'); header('Content-Description: Quran Download'); ob_clean(); flush(); # begin download readfile($fullpath) or die("error!"); exit; ---- Server IP: 64.71.164.2 Probable Submitter: 69.216.99.169 ---- Manual Page -- http://www.php.net/manual/en/function.readfile.php Edit -- https://master.php.net/note/edit/82597 Del: integrated -- https://master.php.net/note/delete/82597/integrated Del: useless -- https://master.php.net/note/delete/82597/useless Del: bad code -- https://master.php.net/note/delete/82597/bad+code Del: spam -- https://master.php.net/note/delete/82597/spam Del: non-english -- https://master.php.net/note/delete/82597/non-english Del: in docs -- https://master.php.net/note/delete/82597/in+docs Del: other reasons-- https://master.php.net/note/delete/82597 Reject -- https://master.php.net/note/reject/82597 Search -- https://master.php.net/manage/user-notes.php
