Nicholas K. Dionysopoulos from Akeeba Backup, Radek Suski from SigSiu.net and many other contributors have been working on a Master htaccess file for many years that you can find it at docs.joomla.org I have attempted to use this several times in the past with mixed results. All servers are not created equal and some of the settings in this file can break your site (temporarily). The version I offer you here works on most hosts.
