Usually a cache plugin works by caching the entire page and serving it altogether to the user.
Unfortunately some Web pages constantly change and the cache needs to re-cache it at small intervals or when it gets updated so it has the latest available version to serve to users. This entirely goes against what a cache system was meant for, but due to a lack of good alternatives, caching systems are still used.
WP Fragment Cache is for these kind of cases where certain page sections get updated at much higher rates than other and the developer wants to cache only the static sections.
This plugin will let a developer decide what to send to the cache and what to compile every time, optimizing page performance based on the content it needs to deliver.
In order to work properly, WP Fragment Cache also needs a persistent cache backend. Some well-known and battle-tested persistent caching backends for WordPress are:
- W3 Total Cache
- WP File Cache
- Memcached Object Cache
- APC Object Cache
- File-Based Caching
- wordpress-redis-backend
