cacheCheckTime property
This property determines how often the system evaluates its cache to see whether it needs expiring. The criteria for whether the cache needs expiring are determined by the cacheSizeLimit and cacheAgeLimit properties.
The valid time units for this property are s (seconds), m (minutes), h (hours), d (days), and w (weeks).
The default value is 1h.
Example
cacheCheckTime=1h
