This plugin is an addon for the WP Rocket caching plugin, designed for site administrators and developers who want to use Redis as a storage backend for their page cache. It replaces the default filesystem storage, which can be beneficial for sites experiencing high traffic or running on servers where disk I/O is a bottleneck.

• Redis Cache Storage: Directly stores and retrieves WP Rocket's generated cache files from a Redis server, moving away from filesystem-based storage.
• Configurable Connection: Supports connection via TCP or Unix socket, with settings for host, port, database, and password configurable through PHP constants for easy integration into different environments.
• Key Prefixing: Includes an optional salt constant to prefix all stored cache keys, helping to prevent collisions and organize data when multiple sites share a Redis instance.
• Performance Consideration: The documentation notes that for some server configurations, such as those using nginx with fast storage, the native nginx setup might be faster, providing a practical consideration for users.
• Dependency Awareness: The plugin hooks into WP Rocket's internal functions and the advanced-cache.php file, meaning its functionality is dependent on WP Rocket's API stability, a factor for users to consider for long-term maintenance.
