Properties

AutoTrimInterval Gets or sets a value that specifies the interval to run automatic cache trimming (clean up). Cached items older than cache's MaxAge setting will be removed when the cache is trimmed.

The default value is 15 minutes. The minimum value is 5 minutes. If the value is 0 or negative, the auto trim will be disabled.


(Inherited from FileCache)
LocationId Gets the unique identifier for the location to store cached files.
(Inherited from FileCache)
LocationString Gets the string representation of location to store cached files.
(Inherited from FileCache)
MaxAge Gets or sets a value that specifies the maximum amount of time to consider a cached item fresh and keep it stored in the cache. Cached items older than this age will be removed when the cache trimming (clean up) runs (when auto trim is run or when cache's Trim() method is manually called).

The default value is 90 days. The minimum value is 10 minutes.


(Inherited from FileCache)
WaitTimeout Gets or sets a value that specifies the maximum amount of time to wait for a cached item to be available (wait for a file lock from other threads or processes to become available, i.e. wait for an ongoing caching of the same file to complete) before giving up on the cache request.

The default value is 5 minutes. The minimum value is 2 minutes.
