Cache Regions

These are the regions which are currently defined in the cache. 'Items' and 'Bytes' refer to the elements currently in memory (not spooled). You can clear all items for a region by selecting 'Remove all' next to the desired region below. You can also Clear all regions which empties the entire cache.
