The "Scheduled preload" feature in the FlyingPress plugin allows for automatic cache preloading (regeneration) at specified time intervals. This feature provides a convenient way to ensure that the cache is updated regularly without manual intervention.
It is important to note that when using this feature, the cache will not be purged; instead, the existing cache will be overwritten during the preloading process. This ensures that the most recent cache version is always available for serving.
It is recommended to enable the "Scheduled preload" feature only when facing any nonce issues or when content is updated in a non-WordPress way. This helps to prevent any potential errors or problems with the cache that may occur if the cache is not updated on time.
