note 32109 added to function.readfile

Hi guys,when I using readfile() to download some *.msi files at client PC with win2000 OS and NetScape6/7 browser ,I found it doesn't work well. the error message is "warning :readfile("http//..../a.msi")-No Such File or Directory".or"warning :readfile("/www/htdocs/..../a.msi")-No Such File or Directory" In fact,the file is exist.because it work well when browser is Netscape 4.x , at this time I using readfile('/www/htdocs/.../a.msi').but if path is "http://.../a.msi",Netscape4.x can't work neither. my code as below: <? $url="http://192.168.0.4/down/a.msi"; $path="/www/htdocs/down/a.msi"; Header("Content-type: application/octet-stream"); Header("Content-Disposition: attachment; filename=a.msi"); readfile($url); //readfile($path); ?> -- http://www.php.net/manual/en/function.readfile.php http://master.php.net/manage/user-notes.php?action=edit+32109 http://master.php.net/manage/user-notes.php?action=delete+32109 http://master.php.net/manage/user-notes.php?action=reject+32109
