Abstract

A communication device may communicate with a data processing device via a communication line. The data processing device may include client applications configured to execute communications by using multisession communication. The communication device may establish a session with a specific client application among the client applications via the communication line, and receive an HTTP request from the specific client application. The communication device may transmit an HTTP response to the specific client application via the established session. The transmission may include transmitting first disconnection instruction information to the data processing device in a case where the communication line used to receive the HTTP request is a line that is not capable of the multisession communication. The first disconnection instruction information may be information for causing the data processing device to disconnect the established session after transmitting the HTTP response.
