Property Value

Type: TimeSpan
The default value is Cache.NoSlidingExpiration.

Remarks

If the slidingExpiration property is set to NoSlidingExpiration, sliding expiration is disabled. If you set the slidingExpiration parameter to less than Zero, or the equivalent of more than one year, an ArgumentOutOfRangeException is thrown when you will try to add or insert the CacheItem. You cannot set both sliding and absolute expirations on the same cached item. If you do so, an ArgumentException is thrown when you will try to add or insert the CacheItem.
