Server and computer program for server for establishing a continuous connection with a communication device to provide screen data

A non-transitory computer readable storage medium storing a computer program for a server including memory and a computer, the computer program comprising instructions that, when executed, cause the computer to function as:

• a connection establisher configured to establish a continuous connection with a communication device in response to a first instruction being received from an external device and configured to not establish a new continuous connection with the communication device in response to a second instruction being received from the external device in the continuous connection established with the communication device, the first instruction indicating a start to provide a first type of service related to a communication device, the second instruction indicating a start to provide a second type of service related to the communication device, the continuous connection being used to perform server-push communication with the communication device;
• a first determiner configured to, in response to a service stop request being received from the external device, determine whether the second type of service related to the communication device is currently provided, using status information indicating a status of providing service stored in the memory;
• a first screen data transmitter configured to transmit first screen data for displaying a first setting screen to the external device in response to the first determiner determining that the second type of service is not currently provided, the first setting screen including a disconnection button to disconnect the continuous connection;
• and
• a second screen data transmitter configured to transmit second screen data for displaying a second setting screen to the external device in response to the first determiner determining that the second type of service is currently provided, the second setting screen not including the disconnection button.
