A method for managing contents of a web site. A request to access a web site is received from a requestor, wherein the web site comprises a sparse tree directory comprising elements used to build the web site. The sparse tree directory comprises a web site page hierarchy located at the root directory of a shape hierarchy, wherein the web site page hierarchy comprises a directory structure of the web application and the shape hierarchy defines user shapes accommodated by the web application. The sparse tree directory also comprises a first subdirectory corresponding to a first value of a dimension and a second subdirectory corresponding to a second value of the dimension, wherein the first subdirectory comprises a first element and the second subdirectory comprises a second element. A shape of the requestor is generated, wherein the shape defines elements that can be accommodated by the requestor. The sparse tree directory is cached. The sparse tree directory is searched for elements defined by the shape. A response to the request is created based on the shape.

This invention provides for an apparatus and method to associate a subscriber with one of many port bundles in an aggregation device. The method reserves one of the port bundles for the subscriber if the subscriber was not assigned a port bundle, changes the original source port number in a data packet to a port bundle number, modifies the subscriber address to an assigned aggregation address, and issues a request to a remote management device for authentication of the subscriber. Once a response is received from the management device including the authentication or unauthentication of the subscriber, the subscriber is mapped with the reserved port bundle in a port bundle object and the reserved port bundle is then assigned to the subscriber. The apparatus has at least one source port to receive a data packet, several port bundles coupled to the source port, each port bundle having a memory with a port bundle object to associate the subscriber with one of the port bundles, a processor coupled to the port bundles, and an output port coupled to the processor.
