note 115548 deleted from function.symlink by salathe

Note Submitter: koval at apisys.pl ---- In addition to note posted by olszewski_marek at yahoo dot com: You could delete the symlink after few seconds - even if file is quite large, OS should store it in memory for http server to properly serve it. Here's how: <?php // Make sure script keeps executing even if user aborts ignore_user_abort(true); // Create symlink mkdir($downloaddir . $string, 0777); symlink($safedir . $filename, $downloaddir . $string . "/" . $filename); // Redirect client Header("Location: " . $downloadURL . $string . "/" . $filename); // Make sure client gets redirect headers, any output from now on should be ignored by client flush(); ob_flush(); // A bit of timeout sleep(3); // Remove symlink unlink($downloaddir . $string . "/" . $filename); ?> With this approach You're sure that You have no unnecessary symlinks, AND no symlinks are deleted with high concurency. I've tested this on some highly limited hosting service - it saves huge ammounts of resources (symlink itself, but also directory scans). above 10000 downloads in 24 hours - no complaints, no errors reported.
