PROBLEM TO BE SOLVED: To enable resumption of communication without making a user of a terminal device perform complicated operation even if the user once terminated the communication in a communication system including: the terminal device that determines whether or not there is redirection which blocks access to a predetermined communication device and automatically starts communication if there is redirection; and a server device that cancels redirection triggered by detection of the start of the communication.SOLUTION: A server device comprises redirect revival means that detects the resumption of communication at a lower protocol layer than communication by a terminal device of which redirection is cancelled, and revitalizes the redirection of the terminal device triggered by detection of the resumption of communication at the lower protocol layer.SELECTED DRAWING: Figure 5 |
