Abstract
A copy computer includes a storage device which stores a copy of contents from a distribution computer and a module which creates a copy of updated contents based on a copy request and which sends a copy of contents requested by a search computer to a distribution request computer. The search computer includes a module which searches for a copy computer storing the copy of the contents requested by the distribution request computer, a module which forwards a send request to a specified copy computer, and a module which sends the copy request and the copy contents to a predetermined copy computer when the contents are updated. The copy request gives an instruction to create the copy of the updated contents in the storage device of the copy computer.
