Work from the last modified date/time on the file. When you update the file it will change. Though if your files really are static, then there's little point - the OS will do a far better job of caching them than you will. Also, you may also want to have a goosey at the Cache-Control: HTTP header over Expires:. It can give you more control. > How do I use *Header set Expires* (on htaccess) and specifying "in a week"? A quick Google found this: Header set Expires "Thu, 15 Apr 2010 20:00:00 GMT" -- Richard Heyes HTML5 Canvas graphing for Firefox, Chrome, Opera and Safari: http://www.rgraph.net (Updated March 28th) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
