It's a custom 404 page, IIRC. Your 404 page simply looks at the URL, grabs the last part and forwards (using header(), I imagine) to the appropriate page. Many other uses for it, too. One that's written about on PHP.net is using this to make static HTML pages. You have a URL such as domain.com/1234.html, where that page doesn't exist. Your 404 page looks up product 1234 from the database, writes an HTML page to disk called 1234.html, then redirects back to the page. Now subsequent requests for 1234.html pull up the page just created and do not hit the database at all. To "clear" everything, simply delete all of the .html files and they'll be regenerated as they're needed. I'm sure there are other uses... ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
