problem with header-dispotition in IE

Hi all ... I have script that looks like : if(file_exists($filename)){ $len = filesize($filename); //header("Content-type: attachment/pdf"); header('Content-Type: application/pdf'); //header("Content-Type: application/octet-stream"); header("Content-Type: application/force-download"); header("Content-Length: $len"); if(preg_match("/MSIE/", $_SERVER["HTTP_USER_AGENT"])){ header("Content-Disposition: attachment; filename=".$name.".pdf","pdf"); }else { header("Content-Disposition: attachment; filename=".$name.".pdf","pdf"); } //header("Content-Disposition: attachment; filename=personal_inventory_forms.pdf"); readfile($filename); } else { echo $filename ; echo ' ERROR : file is not exist' ; } This script works very well on Mozilla, Opera and Safari..but doesnt work with IE. can someone help me to solve this problem ? thx -- Best regards, adwin www.kuya-kuya.net "There is a story living in us that speaks of our place in the world.
