A method, system, and apparatus are directed towards managing content over a network. A request from a requestor for a resource is received over the network. The request may include a request for resource identified by a Network Resource Identifier (NRI). The request may also include Systems Interconnection (OSI) level 2-7 data. Characteristics of the requestor are determined based on the request. The characteristics are mapped onto a label. A unique key is generated based on the request, the characteristics, and/or the label. A version of the resource to cache is determined based on the request, the characteristics, the label, and/or the unique key. The version of the resource is cached based on the unique key.
