CacheManagerTryGetString Method

Attempt to retrieve a cached data item. Use CacheString(String, String, DateTime, String, String, String) to cache the data. See TryGetTable(String, String, DataTable, NullableDateTime) for retrieving DataTables, or TryGetObject(String, String, Type, Object, DateTime) for retrieving other objects. Together the cacheID and ID should form a unique identifier. Having uniquely identified the item in this manner, the item's expiry and optional signature match are used to determine whether or not to accept the item as a cache hit and return it.
