From the developer
docjojo's own description of Mega Cache, lightly tidied.
Mega Cache is a fast WordPress page caching plugin that stores complete HTML page responses and serves them quickly to repeat visitors.
The free version on wordpress.org uses File storage. Paid versions add additional storage backends such as APCu, Redis, Memcached, MariaDB, and MySQL.
Page caching stores an entire page’s content on the server, allowing it to be served from cache on repeat requests instead of being regenerated from scratch.
Mega Cache installs a drop-in that works with WP_CACHE, so repeat visitors can receive a full HTML response before WordPress boots the full stack. The plugin keeps cache keys and invalidation aligned between the drop-in and WordPress, including saves, terms, and WooCommerce product updates where applicable.
Optional cache statistics and debug views help you verify hits, skips, and storage during testing. Logged-in users, WooCommerce session/cart cookies, and other unsafe states are excluded from the public page cache so personalized views are not shared by mistake.
WooCommerce
- Last viewed products will not work on cached pages and products.
