ATTRIBUTE INFORMATION ACQUIRING METHOD

摘要

This invention can handle a communicable state restored from disconnection of a communication line. According to the invention, if the communication line is disconnected while a client terminal 2 requests to acquire a contents attribute file 47 that corresponds to a set of contents data stored in a hard disk and receives the file 47 and subsequently the communication line restores a communicable state, the client terminal 2 requests accounting status notification information to a portal server 4 and receives accounting status notification images 15 and 16 transmitted to it in response so that it can be notified if the accounting process had been completed by the time when the communication was disconnected while receiving the contents attribute file 47 and subsequently the communication line restored a communicable state by accounting status notification information so that it can reliably handle the situation that arises when the communication line restores a communicable state from disconnection.
