# What is Cache Mode Feature in Kitt Cache Crawler?

The Cache Mode feature is an undocumented LiteSpeed feature that not only speeds up crawling. It also allows to refresh the cache of a URL if the cache is not expired. If the cache is not expired the cache is refreshed by the set TTL. If the cache is expired it is normally warmed up. The cache inventory shows whether the cache was refreshed or warmed up normally. The status of the cache is displayed in the "Cache Status" column. "hit" means that the cache had expired, "refreshed" means that the cache had not yet expired and was refreshed by warmup crawling.
