This plugin enables 'enterprise-class' Google Sitemaps to be easily generated for a Rails site as a rake task, using a simple 'Rails Routes'-like DSL. It allows you to take care of familiar Sitemap issues like: Gzip of Sitemap files, variable priority links, paging/sorting links (e.g. my_list?page=3), SSL host links (e.g. https:), Rails apps which are installed on a sub-path (e.g. example.com/blog_app/) and hidden AJAX routes. It includes a Sitemap Index file so it supports more than the standard 50,000 individual urls (up to a maximum of 2.5 billion), and pings all major search engines on completion (Google, Yahoo, MSN, Ask, SitemapWriter).
Dear Adam, your project has helped me a lot and I find it very sad to hear that you have passed away.
Rest In Peace
