1. An image processing system comprising:
an application server located in the Internet; an image processing apparatus located in a local network connected to the Internet via a firewall; a relay server that relays communication between the image processing apparatus and the application server, the relay server being located in the local network; and a connection mediation server that transmits, to the relay server, a request for a connection to the application server, the connection mediation server being located in the Internet, wherein the connection mediation server comprises a connection request transmitting unit that transmits a connection request to the relay server when receiving a communication start request designating the image processing apparatus from the application server to establish communication between the image processing apparatus and the application server, the relay server comprises: a communication establishing unit that establishes the communication by connecting to the application server in accordance with the connection request from the connection mediation server; a job transferring unit that transfers a job received from the application server to the image processing apparatus; a job identifying unit that identifies a type of the job; and a communication terminating unit that terminates the communication when there is no transmission/reception being performed between the application server and the relay server in accordance with the job type identified by the job identifying unit, and after the communication terminating unit terminates the communication, the communication establishing unit reestablishes the communication by connecting to the application server after receiving data to be transmitted to the application server from the image processing apparatus, and transfers the data.
