摘要:
A method for responding to inquiries from a user by a response support system. A request displaying a second screen is received from a user terminal of the user in which a first screen is being displayed. An inquiry destination of the response support system is identified in the first screen. Screen data pertaining to the second screen and containing an operation object is retrieved. The second screen is configured to be sent to the inquiry destination in response to an operation performed on the operation object by the user. Screen transition information containing screen identifiers of screens previously displayed by the user terminal, including the first screen, is retrieved. The second screen is assembled by inserting the retrieved screen data and the retrieved screen transition information into the second screen. The assembled second screen is sent to the user terminal.
