Abstract

See full text

A file reading scheme in a client-server information communication system, capable of efficiently utilizing files cached into a local file storage region of the client regardless of an environment under which the client is operated. Whether the client is in a state in which an access to the server according to a specified protocol is possible or not is judged when each file transfer request is issued at the client. Then, an access to the server according to the specified protocol is made when it is judged that the client is in a state in which an access to the server according to the specified protocol is possible. On the other hand, a requested file specified by each file transfer request is read from files cached in the local file storage region when it is judged that the client is in a state in which an access to the server according to the specified protocol is not possible.
