Abstract
Techniques relating to caching a content object are disclosed. These techniques include transmitting, from a requestor to a first server, a revalidation request relating to a content object, and receiving, at the requestor from the first server, a response to the revalidation request indicating that the content object is not modified. The response is received at the requestor based on the first server 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 whether to retrieve content object data from any server based on analyzing a metric relating to retrieving the content object.
