The minimum number of content elements in the cache area sufficient to trigger a cache prune action. Specifically, a background process periodically checks whether the content element count statistic (as indicated by the ContentElementCount property) has exceeded this prune number threshold, or whether the content element size statistic (as indicated by the ContentElementKBytes property) has exceeded the prune size threshold (as specified by the PruneThresholdSizeKBytes property). If so, a mandatory prune action gets launched; its purpose is to ensure that cache content remains under the prune threshold levels.

With respect to any given directory, a mandatory prune can be either a full or partial prune (and so, with respect to the cache as a whole, a mandatory prune can be a mixture of full and partial prunes). It is a full prune only when the LRU list needs to be generated. Specifically, it is a full prune in these circumstances: this is the first pruning action for a new cache, and consequently no LRU list yet exists; the LRU list has expired (it is older than 1 day); or a previous prune action exhausted the LRU list. (Note that a partial prune can exhaust the LRU list without satisfying the prune quotas.)

For an overview of cache pruning, see the IContentCacheArea interface. For definitions of pruning terms (full prune, partial prune, LRU list, etc.) and a detailed discussion of pruning, see the PruneAmount property.

Note that, as indicated above, the PruneThresholdSizeKBytes property defines another pruning threshold.
