WP Super Cache is a widely-used WordPress plugin developed by Automattic that enhances website performance by generating static HTML files from dynamic WordPress content. This approach significantly reduces server load and accelerates page delivery to visitors. The plugin offers three caching modes: Expert (leveraging Apache mod_rewrite for maximum speed), Simple (serving static files via PHP without .htaccess modifications), and WP-Cache (caching for logged-in users and dynamic content). Additional features include support for Content Delivery Networks (CDNs), page compression, cache preloading, and scheduled garbage collection to manage outdated cache files. With over 2 million active installations, WP Super Cache is a reliable solution for improving site speed and scalability.
