Dynamic multi-level cache manager
DCFirst Claim
1. A method of caching data, which involves the steps of:
- receiving from one of a plurality of network clients a request for a data item;
creating a private cache uniquely associated with the one network client;
initiating association of the private cache with a shared cache, the shared cache including the requested data item and being associated with a number of the network clients; and
updating the private cache with the requested data item.

Abstract
A method of caching data in a multi-processor computing environment, involves the steps of receiving from one of a plurality of network clients a request for a data item; establishing a private cache uniquely associating with the network client; associating the private cache with a shared cache, the shared cache including the requested data item and being associated with a number of the network clients; and updating the private cache with the requested data item. In one aspect, the shared cache includes a subset of a store of dynamically-variable data, and the method also involves storing in the shared cache a data update received from one of the network clients; receiving from another of the network clients a request for an item of the variable data; and updating the private cache of the one network client with the update data and the requested data item.

10. A caching server for caching data, the caching server comprising:
-
receiving means for receiving from one of a plurality of network clients a request for a data item;
cache establishing means in communication with the receiving means for creating a private cache uniquely associated with the one network client;
cache associating means in communication with the cache establishing means for initiating association of the private cache with a shared cache, the shared cache including the requested data item and being associated with a number of the network clients; and
updating means for updating the private cache with the requested data item.

11. A method of caching dynamically-variable data, which involves the steps of:
-
maintaining a store of dynamically-variable data and a shared cache, the shared cache being associated with a plurality of network clients and including a subset of the data store;
receiving from one of the network clients a data update to the shared cache, and storing the updated data in at least the shared cache;
receiving from one other of the network clients a request for an item of the variable data; and
initiating updating of a private cache associated with the one other network client, the private cache being uniquely associated with the one other network client and including a respective portion of the data subset, the data portion including the requested data item and cache data corresponding to the updated data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

21. A method of caching dynamically-variable data, which involves the steps of:
-
maintaining a store of dynamically-variable data, the data store including one of application data, and user session data;
dynamically establishing a first level cache and a second level cache in response to a request for the stored data, the caches caching data comprising a subset of the stored data; and
dynamically removing at least one of the caches after invalidation thereof. - View Dependent Claims (22, 23, 24, 25)
