Abstract
Techniques relating to caching a content object are disclosed. A first server receives a revalidation request, relating to a content object, from a requestor. It is determined that metadata, relating to the content object, is stored in a cache associated with the first server. In response, the first server determines not to retrieve the content object from a second server. The content object is not stored in the cache. A response to the revalidation request, indicating that the content object is not modified, is transmitted from the first server to the requestor, based on analyzing the metadata.
