Information processing system, client device, and control method

摘要

An image forming apparatus establishes a first network connection using a network protocol to enable transmitting of a request that is issued by taking the server apparatus for the starting point through a firewall to the image forming apparatus. The client server apparatus transmits an instruction through the first network connection to establish a second network connection corresponding to an application installed on the image forming apparatus after establishment of the first network connection. The image forming apparatus establishes the second network connection in response to the instruction transmitted from the print server.

主权项

1. An information processing system in which a client device and a server apparatus communicate through a firewall,
wherein the client device comprises: an establishment unit configured to establish a first network connection using a network protocol to enable transmitting of a request that is issued by taking the server apparatus for the starting point through the firewall to the client device, the server apparatus disposed outside the firewall, wherein the server apparatus comprises: a transmitting unit configured to transmit an instruction to establish a network connection corresponding to an application installed on the client device, and wherein, after the first network connection is established by the establishment unit, the client device receives the instruction transmitted from the server apparatus through the first network connection, and the establishment unit establishes a second network connection in accordance with the received instruction, wherein the establishment unit provided in the client device establishes the first network connection through the connection of a first network protocol, and establishes the second network connection through the connection of a second network protocol, wherein the second network protocol is used in communication of information required for execution of processing corresponding to the request by taking the server apparatus for the starting point, between the server apparatus and the application, and wherein the first network protocol controls a connection/disconnection timing of the second network protocol.
