LRUCache Object

For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.

Note

The LRUCache object is obsolete; instead, use ASP.NET and/or Catalog API caching.

Use this object to support the creation, storage, and retrieval of name/value pairs, referred to as elements, from a cache in memory. The LRUCache object functions similarly to the Dictionary object, except that it only stores a limited number of elements, and internally ranks them according to use. When the cache is full and a new element needs to be added, the least recently used element is removed from the cache to make room for the new element.
