Abstract
Systems and methods for publishing objects (e.g., pages and/or fragments) include assigning expiration times to different versions of objects and determining a plurality of objects which should be published atomically, that is, together in a single action. Then, the invention includes computing updated versions of the plurality of objects and atomically publishing the updated versions wherein the updated versions are not available until after expiration times corresponding to previously published versions of at least one of the plurality of objects (e.g., a cached object) have elapsed. Advantageously, clients attempting to access related cached objects over an information network such as the Internet will not be presented with versions of related objects that are inconsistent with one another.
