I've been looking for an easy way to point search engines to the sitemap.xml file in the root of the website. I've been using Google Sitemap Lite in combination with Navee or Structure. And it's generating sitemap.xml output like a charm.
But I've put the code in a template group named "sitemap". So I need to edit the .htaccess file, so the /sitemap.xml url points to /index.php?/sitemap. I couldn't get it to work...
