This document contains configuration settings for mod_rewrite and security rules to protect a Joomla site from common exploits. It begins with notes explaining that the 'Options +FollowSymLinks' line may need to be commented out depending on server configuration. It then lists rewrite rules to block scripts trying to base64 encode data, insert script tags, or modify PHP global variables via the URL. Custom redirects and rewrite rules are also included to internally rewrite all requests to the index.php file, following Joomla's front controller pattern. PHP settings are set at the bottom to limit execution time and memory usage.
