COMMUNICATION SYSTEM, COMMUNICATION DEVICE AND COMMUNICATION MANAGEMENT METHOD

PROBLEM TO BE SOLVED: To achieve high-level access management in a network having a registry server and a repository server. SOLUTION: In the communication system, a communication device 22 inserts its own IP (Internet Protocol) address into an HTTP (Hypertext Transfer Protocol) header of a registry retrieval response (3) as registry access information. A communication device 21 acquires a URI (Uniform Resource Identifier), meta information, the registry access information, and repository access information from a registry retrieval response (2). The communication device 21 inserts the meta information, the registry access information, and the repository access information into an HTTP header of a content acquisition request (3) based on a URI of the content acquisition request (3). A communication device 23 extracts the meta information, the registry access information, and the repository access information from the content acquisition request (3), and uses them for determining whether to permit transfer a content acquisition response (4).
