    <p>The rewrite rule you have there is fine... except you should probably add a condition to check and make sure the REQUEST is not "handle.php" - otherwise you may get a redirect loop.</p> <p>Now, in your handle.php file - this is handling ALL files request in that folder.</p> <p>In handle.php, you can use <code>$_GET['path']</code> to get the requested file name. While in handle.php, you can include your authentication checks. If the authentication check passes, you can then continue to <code>readfile</code> to the user. An example of handle.php:</p> <pre><code>&lt;?php set_time_limit(0); session_start(); include "../some_functions_auth_file.php"; // NOTE: better file checking should be implemented here. We're using basename() for now. $file = !empty($_GET['path']) ? basename($_GET['path']) : false; if($file === false || !file_exists($file)) die("Invalid file."); if(user_is_authenticated()) { header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT"); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false ); header("Pragma: no-cache" ); header("Content-Type: application/octet-stream"); header("Content-Length: " .(string)(filesize($file)) ); header('Content-Disposition: attachment; filename="'.$file.'"'); header("Content-Transfer-Encoding: binary\n"); readfile($file); exit; } else { header("Location: ../login.php"); } ?&gt; </code></pre> <p><em>Note that this is very basic and untested</em></p> <p>Now, if you don't want to use <code>readfile</code> (because it's, well, slow), then perhaps you could set an Apache environment variable... then, while in .htaccess, you could check if that variable exists - and if so, allow the download. Otherwise redirect the user to a login.</p>

    2. CONo - that would take some extra coding and is fairly slower as it uses fread. But here's a good example if you must: http://www.richnetapps.com/php-download-script-with-resume-option/

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
