File through script

hi, i have the following problem with IE5.0, IE5.5, PHP4, Apache, Linux: the user should download ("save as") the file /home/test/info.txt. the user should not see the file in his browser. download-file: /home/test/info.txt (it's a "real" text-file) link for the download: <a href="download.html?download_file=info.txt&download_path=/home/test">downloa d</a> script that handles the download (download.html): <? header ("Content-Type: application/octet-stream"); header ("Content-disposition: attachment; filename=".$download_file""); readfile($download_path."/".$download_file); ?> problemes: - IE5.0: after the "save as"-window appeared, the browser is still active (looking for the download.html-file) - IE5.5: the file info.txt is always shown in the browser-window thanks stefan PS: NetscapeNavigator 4.08: everything works fine
