Abstract: Systems and methods are provided for requesting a resource over at least one network. The system includes a network entity, such as a gateway or an origin server, capable of receiving a resource request for the resource. The resource request includes a group header identifier such that the network entity is capable of identifying at least one header field associated with the group header. By identifying the header fields associated with the group header, the resource request can be processed in accordance with the associated header fields. Before receiving the resource request, the network entity can be capable of receiving a earlier request from a terminal, where the earlier request includes at least one header field and a call for associating the at least one header field with a group header identifier. The network entity can then be capable of associating the header fields with a group header identifier.

Abstract: A system and method for progressively downloading a content file. An electronic device including a browser application, and a server including a metafile and an associated content file. When a user desires to progressively download the content file to the electronic device, the electronic device reads the metafile to determine whether the content file is capable of being subject to progressive downloading. If the content file is capable of being subject to progressive downloading, the content file is progressively downloaded to the electronic device.

Abstract: Disclosed is a method to deliver a set of song-related information to a terminal associated with a subscriber of a content provisioning system. The method includes establishing a subscriber profile for specifying at least a frequency at which the content provisioning system is to download to the subscriber at least one list of content, in the preferred invention at least one list of songs, that is updated in accordance with at least one criterion. The method further downloads the at least one song list to the terminal at a time that is based on the subscriber profile. Also disclosed is a content provisioning system, a network server and a terminal that operate in accordance with the method.
