A method loads a resource in a software application. The software application comprises an ordered search path identifying at least one of a plurality of resource containers. Each of the resource containers includes a timestamp and an index in the ordered search path. The method includes loading a resource from an originating resource container, the originating resource container having an index in the ordered search path, identifying a set of resource containers in the ordered search path, each of the set of resource containers having an index less than or equal to the index of the originating resource container, generating a cached resource as a copy of the loaded resource, the cached resource comprising the index of the originating resource container and a cached resource timestamp, the cached resource timestamp corresponding to a maximum timestamp of the resource containers in the set of resource containers, and marking the cached resource as invalid in response to a determination that a resource container in the set of resource containers has a timestamp later than the cached resource timestamp, and the identified resource container comprises the cached resource.
