Disclosed is a method and apparatus for delivering information of interests from content providers to clients via a data network. A network architecture includes two types of edge servers, referred to as forward proxy servers and reverse proxy servers. The forward proxy servers are assigned to serve particular clients with respect to particular information and the reverse proxy servers are assigned to serve particular forward proxy servers with respect to particular information. Each of the forward proxy servers stores information identifiers associated with information for which the forward proxy server is assigned to serve to at least one client. Each of the reverse proxy servers stores information identifiers and the associated forward proxy servers that the reverse proxy server is assigned to serve with respect to information associated with the information identifiers. Upon receipt of updated content, the reverse proxy servers send the updated content to those forward proxy servers that the reverse proxy server is assigned to serve with respect to the received updated content. The forward proxy servers then provide the updated content to the clients to which they are assigned, either by responding to a request from those clients or by pushing the information to those clients. Network load balancing is provided by a controller network node for controlling the assignments of clients to forward proxy servers and the assignments of forward proxy servers to reverse proxy servers.
