This contribution is taken from http://addons.oscommerce.com/info/6583 Thanks to Jack_mcs for providing the upgraded versions. The problem with Jack_mcs contribution, which was originally authored by Chemo, was that all the links and database actions were hard-coded. This created a problem if you were trying to use this with FWR Media's Ultimate SEO URL. FWR Media does provide a Google XML Sitemap SEO however, that version is a bit outdated. The attached version is based on Jack_mcs's latest version 1.5 Code has been tested to work for v 2.2 and v 2.3 of osCommerce.
