US 2003/0120867 A1 · Context-sensitive caching

Abstract

A method of caching contextually variant objects in a common cache. The method can include identifying an object type for a requested object and determining whether the requested object has an object type which is specified among an enumerated set of cacheable object types which can be stored in the common cache. Importantly, each cacheable object type can have an associated context. If the requested object has an object type which is specified among the enumerated set of cacheable object types, a cache key can be computed for the requested object using cache key formulation rules for the associated context. Finally, the requested object can be retrieved from the common cache using the formulated cache key. Notably, in one aspect of the invention, the method also can include the step of invalidating individual objects in the common cache according to corresponding cache policies of associated contexts.

Dependent claims

A context-sensitive caching system comprising:

a common cache;
a common caching engine configured to write cacheable objects to said common cache, said common caching engine being further configured to retrieve cacheable objects stored in said cache;
a shared name generator configured to formulate cache keys for locating said cacheable objects written to said common cache;
a plurality of configuration specifications, each said configuration specification specifying a caching policy for a single context;
and,
a plurality of plugable context providers, each said plugable context provider providing said common cachine engine with an interface to corresponding ones of said configuration specifications.
