Remarks
The Cache class uses an object of Leadtools.Medical.Caching.Storage.IStorageProvider to store and retrieve cached items. Use the one of the overloaded constructors to create an object of this class.
The cache store will be maintained by deleting expired items, this is decided by the ItemExpireDuration. If the cache store is full and the CurrentSize exceeded the BytesLimit and there are no items expired then items with the lowest priority System.Web.Caching.CacheItemPriority will be deleted until the cache CurrentSize is less than the BytesLimit.
To force the Cache to update and maintain the cache store call the Update method. The Cache class internally calls this method regularly and after adding or inserting new items.
