OK, then we're on the same page here (no pun intended). When running a PHP script that sets headers, the only requirement is that you set the headers before _any_ content has been displayed. Basically, that means that the very first characters of the PHP file must be "<?php" and no echos or other content-generating commands are run until after all headers are set. There's no requirement to call echo, the headers are sent even if your page contains no content at all. > I would print a directory listing of a directory containing downloadable > files > to the browser with php, where each file listing is wrapped in an anchor > that has the href value set to a script with a query attached: something > along the lines of <a href="downloader.php?file=[file to download]">[file > to download]</a> Perfectly doable. Downloader.php simply needs to set the headers, interpret the GET variable, and stream the file. Listing the directory is a separate problem, and you'll surely find plenty of tutorials by searching online. > I am thinking of any file type: .pdf, .rtf, .swf, .doc, mpg, mpeg, mp3, > binary, as well as plain text, whatever Also easy. Set the Content-Type header to the file's corresponding MIME type. --Sean
