A computer-readable recording medium containing an application management program for automatically performing version management to surely manage versions of a client application that communicates with a server application. A communication request monitor acquires a communication request issued from a terminal device to a server, and extracts version information of a client application from the communication request. An upgrade determination unit determines whether the extracted version information shows the latest version, and determines that upgrade is necessary if the version is not the latest version. A setting file transmitter sends the communication request to the server if the upgrade determination unit does not determine that the upgrade is necessary. If the upgrade is necessary, on the contrary, the setting file transmitter discards the communication request and sends the client application setting file for the latest version to the terminal device sending the communication request.
