Relay server and relay communication system

摘要

A relay server can collectively copy a plurality of shared resources separately held by client terminals to a terminal that belongs to the relay server by performing a simple operation. The relay server includes a shared resource information registration unit. The shared resource information registration unit stores shared resource information when a resource is shared among a plurality of client terminals. The shared resource information includes resource information, hierarchical structure information regarding a hierarchical structure of the resources, and account information of a resource sharing terminal that is a client terminal that shares the resource. When the shared resource information is specified by the resource sharing terminal such that the resource included in the prescribed shared resource information may be output to an output destination in accordance with the hierarchical structure information, the relay server transfers the resource that is included in the specified shared resource information and that can be handled by another resource sharing terminal to the resource sharing terminal.
