Nginx Cache is a utility tool designed for WordPress users, allowing for automatic purging of the Nginx cache whenever content changes. This is essential for maintaining up-to-date website performance and ensuring that visitors see the latest content without delay. The plugin supports various cache types, including FastCGI, Proxy, and uWSGI, making it versatile for different server configurations.

The functionality is straightforward: it leverages the WordPress Filesystem API to operate without requiring additional credentials. However, it is important to note that Nginx and PHP must run under the same user account, or PHP must have the necessary write access to the Nginx cache path. This ensures seamless integration and optimal performance of the cache management process.
