Abstract
A method of operating a router is disclosed. The method may include updating a data object to or from a router cache of the router. For example, the router may store or distribute the data object by determining whether a client device in a local network established by the router stores a version of the data object different from a version on the router cache. For another example, the router may store the data object based on a cacheable tag associated with the data object, the cacheable tag indicating that the data object is intended by a content server system to be cached in the router cache.
