Abstract:
1. A communication relay apparatus that relays communication between an external network and an internal network, the apparatus comprising: a judgment unit, implemented by at least one hardware processor, that receives from a terminal on the external network a communication start message indicative of start of communication to judge whether or not the communication start message includes a specific application algorithm that requests a connection to a specific application within the internal network; an acquisition unit, implemented by said at least one hardware processor, that, if the judgment unit judges that the communication start message includes the specific application algorithm, identifies an operation type of the specific application based on a random number in the communication start message, and acquires information about a proxy that is set according to the identified operation type; a proxy unit, implemented by said at least one hardware processor, that controls an operation of the specific application instead of the terminal based on the information about the proxy acquired by the acquisition unit; and a transmission unit, implemented by said at least one hardware processor, that inserts the specific application algorithm included in the communication start message in a response message responsive to the communication start message, and transmits the response message to the terminal.
