Abstract

An intermediary server apparatus relays an information readout request from a terminal to an origin server, and returns information provided by the origin server to the terminal. The intermediary server apparatus previously assigns a first user ID to a user to discriminate each user. The origin server assigns a second user ID to the user to identify the information readout request. In the intermediary server apparatus, a memory correspondingly stores the first user ID and the second user ID. A communication unit retrieves the second user ID corresponding to the first user ID from said memory in case of receiving the information readout request including the first user ID from the terminal, and sends the information readout request including the second user ID to the origin server.

Claims

1. An intermediary server apparatus which relays an information readout request from a terminal to an origin server, and relays information provided by the origin server to the terminal, comprising:

a memory configured to correspondingly store a first user ID to discriminate each user and a second user ID to discriminate each information readout request, the second user ID being assigned by the origin server to the user to identify the information readout request;

a communication unit configured to retrieve the second user ID in response to the first user ID from said memory in case of receiving the information readout request including the first user ID from the terminal, and to send the information readout request including the second user ID to the origin server.

2. The intermediary server apparatus according to claim 1,

wherein a plurality of origin servers each provide information in case of receiving the information readout request, and each origin server uniquely assigns the second user ID to the terminal.

3. The intermediary server apparatus according to claim 2,

wherein a plurality of terminals each input the first user ID from the user in case of sending the information readout request.

4. The intermediary server apparatus according to claim 1,

wherein said memory additionally stores a server name of the origin server which assigns the second user ID in correspondence with the first user ID and the second user ID.

5. The intermediary server apparatus according to claim 4,

further comprising a control unit configured to generate the first user ID if the information readout request does not include the first user ID and the first user ID is not input by the user through the terminal, and to send the first user ID to the terminal,

wherein said memory newly stores the first user ID.

6. The intermediary server apparatus according to claim 4,

wherein said communication unit sends the information readout request without the second user ID to the origin server if said memory does not store the second user ID corresponding to the first user ID.

7. The intermediary server apparatus according to claim 6,

wherein said memory newly stores the second user ID and the server name in correspondence with the first user ID, if the information provided by the origin server includes the second user ID.

8. The intermediary server apparatus according to claim 3,

further comprising a history memory configured to correspondingly store the first user ID and a history of information readout requests sent to the plurality of origin servers, the information readout requests being received with the first user ID from the terminal.

9. The intermediary server apparatus according to claim 8,

wherein said communication unit retrieves the history corresponding to the first user ID from said history memory in case of receiving a history presentation request including the first user ID from the terminal, and sends the history to the terminal.

10. The intermediary server apparatus according to claim 9,

further comprising a correspondence relation memory configured to correspondingly store an attribute of a terminal and link data for the terminal to read out information, if information provided by the origin server includes the attribute and the link data.

11. The intermediary server apparatus according to claim 10,

wherein said communication unit updates the history by referring to the link data, if said correspondence relation memory stores the link data corresponding to the attribute of the terminal, and sends the updated history to the terminal.

12. The intermediary server apparatus according to claim 4,

wherein said memory additionary stores a password in correspondence with the first user ID, the server name, and the second user ID, and

wherein said communication unit relays the information readout request from the terminal to the origin server, if a password of the first user ID input by the user through the terminal coincides with a password of the same first user ID stored in said memory.

14. The information providing method according to claim 13,

wherein a plurality of origin servers each provide information in case of receiving the information readout request, and each origin server uniquely assigns the second user ID to the terminal.

15. The information providing method according to claim 14,

wherein a plurality of terminals each input the first user ID from the user in case of sending the information readout request.

16. The information providing method according to claim 13,

further comprising:

additionally storing a server name of the origin server which assigns the second user ID in correspondence with the first user ID and the second user ID in the memory.

17. The information providing method according to claim 16,

further comprising:

generating the first user ID, if the information readout request does not include the first user ID and the first user ID is not input by the user through the terminal;

sending the first user ID to the terminal; and

newly storing the first user ID in the memory.

18. The information providing method according to claim 16,

further comprising:

sending the information readout request without the second user ID to the origin server if the memory does not store the second user ID corresponding to the first user ID.

19. The information providing method according to claim 16,

further comprising:

additionally storing a password in correspondence with the first user ID, the server name and the second user ID in the memory; and

relaying the information readout request from the terminal to the origin server, if a password of the first user ID input by the user through the terminal coincides with a password of the same first user ID stored in the memory.

13. An information providing method for relaying an information readout request from a terminal to an origin server, and for relaying information provided by the origin server to the terminal, comprising:

correspondingly storing a first user ID to discriminate each user and a second user ID to discriminate each information readout request in a memory, the second user ID being assigned by the origin server to the user to identify the information readout request;

retrieving the second user ID in response to the first user ID from the memory in case of receiving the information readout request including the first user ID from the terminal; and

sending the information readout request including the second user ID to the origin server.

20. A computer program product, comprising:

a computer readable program code embodied in said product for causing a computer to relay an information readout request from a terminal to an origin server, and to relay information provided by the origin server to the terminal, said computer readable program code having;

a first program code to correspondingly store a first user ID to discriminate each user and a second user ID to discriminate each information readout request in a memory, the second user ID being assigned by the origin server to the user to identify the information readout request;

a second program code to retrieve the second user ID in response to the first user ID from the memory in case of receiving the information readout request including the first user ID from the terminal; and

a third program code to send the information readout request including the second user ID to the origin server.
