Nginx Cache Controller is a WordPress plugin designed to enhance the management of Nginx proxy server caches. This utility offers several key features that streamline cache control, including the ability to automatically delete caches upon post updates and manage cache expiration periods. Notably, it ensures security by making comment authors’ information ajaxed to prevent caching and sends no-cache headers for password-protected posts. Additionally, it provides an admin bar menu for easy cache deletion, making it user-friendly for site administrators.

The plugin supports WP-CLI, allowing users to flush all proxy caches and view lists in various formats, enhancing its functionality for those comfortable with command-line interfaces. It is available in multiple languages, including English, Japanese, and Vietnamese, catering to a diverse user base. Although the plugin is free to use, it comes with a disclaimer regarding the lack of operational guarantees or support, making it essential for users to understand its limitations before implementation.
