KM: Thinking off the top of my head (not always the best for me) -- why not give the user a static url AND a key? The static url would have a php program sitting there waiting for a user to come along and provide the correct key. After which, your program would then create the file (in a random named folder); provide the user with a link; and clean-up after he's done. That way you have the control over what's happening. The key approach handles security and when to clean-up. hth's tedd -- ------------------------------------------------------------------------------------ http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
