System and method for identifying web objects unworthy of being cached

摘要

A caching device is configured to determine whether an object received or currently stored at the caching device should be (or continue to be) cached at the caching device, even if the object is otherwise cacheable. If so, the object is cached (or retained) at the caching device, otherwise, it is not. The determination as to whether or not the object should be cached or, if already cached, retained at the caching device may be made on the basis of a worthiness determination which evaluates the object on the basis of one or more parameters or attributes of the object, which worthiness may be one part of an overall value determination for the object.

1. A computer-implemented process, comprising:
determining, according to one or more criteria, whether or not an otherwise cacheable object received at a caching device should be cached at the caching device; and if so, caching the object at the caching device, otherwise, not caching the object at the caching device, wherein the one or more criteria consider a cache worthiness of the object in combination with a resource availability of the caching device, and wherein when the resource availability of the caching device is high, objects with a low cache worthiness are allowed to be cached in the caching device and when the resource availability of the caching device is low, only objects with a high cache worthiness are allowed to be cached in the caching device.
