> # Compatibility Security: Caching Realms

> Related Tasks Related Topics

> The Caching realm works in Compatibility security with the File realm, alternate security realms, or Custom security realms to fulfill client requests with the proper authentication and authorization. The Caching realm stores the results of both successful and unsuccessful realm lookups. It manages separate caches for users, groups, permissions, ACLs, and authentication requests. The Caching realm improves the performance of WebLogic Server by caching lookups, thereby reducing the number of calls into other security realms. Note that the use of the Caching realm is deprecated.

> When one or more Caching realms are configured, this Caching Realms page displays key information about each of them. To create a Caching realm, click the New button. To configure an existing Caching realm, click the name of the realm.
