You might not know that using such popular extensions, as OSMap,XMap, MapX without caching can down your server completely. It iseasy to make your site unresponsible by doing a school DDOS (HTTPflood) attack from a mobile phone, sitting in front of TV. This isbecause sitemap generators require a lot of server resources to runheavy SQL queries for building the sitemap. I wrote these 100strings of code (just 100, no more) to make the sitemap generatorsfast and secure, because there were not clean solutions for XMapbased generators that would work without errors. This plugin islike the standart Joomla! Page Cache plugin, but only for sitemapgenerators. It does not run SQL queries to get the cache, it doesnot run SQL queries to store the cache – it uses your systemconfiguration.
