Download file

Hi I have problems with downloading files from my web application in php. Here is the code from download.php <? if (isset($dload)) { if ($dload=="cdrs") // { $filename="./dload_files/temp.txt"; // now create file, and load some data from mssql in it - it is ok $fp=fopen($filename,"w"); write_data($fp); fclose($fp); } $len=filesize($filename); header('Cache-Control: no-cache, must-revalidate'); header('Pragma: no-cache'); header("Content-type: application/download"); header("Content-Length: $len"); header("Content-Disposition: attachment; filename=\"$filename\""); $fp=fopen($filename, "r"); fpassthru($fp); exit; } ?> download.php is called from another page I get the save as dialog box , but filename is not temp.txt but download with no extension. I have heard this is bug in IE about content-disposition headers. Anyone can help here? Radovan
