Different parts of a representation are controlled by different cache expiration times. A differential control scheme may adopt a hierarchical control structure in which a subordinate level control policy can override its superordinate level control policies. Different parts of the representation can be updated to a cache separately. Differential cache control can be implemented by programming a cache control directive in HTTP/1.1. Respective cache expiration time and their control scopes can be specified in a response header and/or response document provided by a server."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Differential cache for representational state transfer (REST) API","description":"System and method of differential cache control.
