Abstract
Techniques relating to caching a content object are disclosed. These techniques include receiving, at a first server from a requestor, a revalidation request relating to a content object. The techniques further include determining that metadata describing one or more characteristics of the content object is stored in a cache associated with the first server and that the content object is not stored in the cache, and in response: determining, at the first server, whether to retrieve content object data from any server based on analyzing a metric relating to retrieving the content object, and transmitting from the first server to the requestor, based on analyzing the metadata, a response to the revalidation request indicating that the content object is not modified.
