WP Super Cache generates static HTML files from dynamic WordPress content, speeding up load times by serving pre-rendered pages instead of processing requests dynamically.
WP Super Cache is a free, open source WordPress plugin that creates static HTML files from your dynamic WordPress content. This speeds up your site's load times by serving these pre-rendered pages to visitors instead of processing every request dynamically through PHP and the database.
When a visitor comes to your site, WP Super Cache will check if there is already a static HTML version of that page saved on your server. If there is, it will serve that file, allowing it to load much faster since it doesn't have to run all the usual WordPress PHP scripts and database queries.
If there isn't a cached version, the normal WordPress scripts will generate the page as usual, and WP Super Cache will save a cached static version to serve for future requests. This means it works seamlessly in the background to speed up your site without breaking any functionality.
WP Super Cache has advanced options like mod_rewrite rules for Apache, reverse proxy and CDN support, and the ability to exempt certain pages from caching. You can also clear or preload caches manually or on a cron schedule.
Overall, WP Super Cache is a simple yet powerful caching plugin that can dramatically improve WordPress site performance. It's a popular choice trusted by over 2 million WordPress sites and is highly recommended for any site looking to speed things up.
