Abstract: A system is provided for streaming content to individual subscribers using podcasting technology. Each subscriber to the system is assigned a unique URL number that he uses to obtain content from a server. The server maintains a set of rules or attributes associated with each subscriber, said rules governing or controlling the download of the content. Some rules may pertain to the number of times a subscriber can download content. Other rules are applicable for multipart content transfer and allow each subscriber to obtain the content parts independently of the other subscribers. The system can also receive podcasts from several podcasters, cache the podcasts and deliver them to a subscriber in a concatenated form on demand.
