Abstract

Methods and apparatuses for dynamically locating resources. In one aspect of the invention, a method to retrieve a resource for a digital processing system includes: receiving a request for a resource; downloading a first version of the resource from a server through a network connection to satisfy the request if the first version of the resource is retrievable through the network connection; and loading a second version of the resource from a storage device of the digital processing system if the first version of the resource is not retrievable through a network connection. In one example, downloading the first version is performed in response to a determination that the first version of the resource is different from a second version of the resource on a storage device of the digital processing system.
