    33 * Plugin Name:       Cache Shark
    4  * Description:       Make your site fast with free, no-nonsense page caching. Cache Shark saves a static copy of each public page and serves it before WordPress, your theme and your plugins even load. It clears only the pages that changed when you publish or update content, warms the cache in the background from your sitemap, cleans up expired files and adds GZIP and browser-caching rules on Apache and LiteSpeed. Safe by default, with nothing to configure.
    5  * Version:           0.1.0
     4 * Description:       Free, open-source page caching for WordPress.
     5 * Version:           0.2.0
    66 * Requires at least: 6.9
    77 * Requires PHP:      7.4

    2323* **Expired page cleanup** keeps the cache folder from growing forever.
     24* **Lazy loading** for images and embedded videos or maps, so offscreen media loads only when a visitor scrolls near it. Off by default; the first images on each page are never delayed.

    6970Preloading uses WP-Cron, which only runs when someone visits your site. On quiet sites, or if `DISABLE_WP_CRON` is set, add a server cron job that requests `wp-cron.php` every few minutes.
