I would recommend looking into a webserver that supports offloading the file download to the webserver via fastcgi: - nginx (preferred) using X-Accel-Redirect header - lighttpd using X-Lighttpd-Sendfile header - apache has a module mod_sendfile or something, but I don't recommend apache for anything anymore not sure if other webservers have it or not. But basically it allows you to use PHP/application level logic to validate if the user has access, and then tells the webserver "okay, now send the file" and releases PHP/application level from having to spoonfeed the file using things like readfile() and keeping the PHP thread/whatever open -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
