upon receipt of the page retrieval request retransmitted from the client terminal, the transfer unit returns a page created by the page creation unit to the client terminal.

4. The providing apparatus according to claim 1, further comprising:

a data retrieval unit for, upon receipt of the page retrieval request from the client terminal, acquiring data from an external server connected to an external network, the external network not preventing entry of a data retrieval request from the providing apparatus; and

an external data transmission unit for transmitting data retrieved by the data retrieval unit to the client terminal, wherein

upon receipt of the page retrieval request from the client terminal, the page return unit returns a page including code, the code to be executed on the client terminal, the code causing the client terminal to transmit the data transmission instruction to an internal server, the internal server as well as the client terminal being connected to an internal network, the internal network preventing entry of a data retrieval request from the providing apparatus.

5. The providing apparatus according to claim 1, further comprising:

an input unit for receiving input of specification of data from the client terminal, the data to be incorporated into a page provided by the providing apparatus, wherein

upon receipt of a page retrieval request from the client terminal, the page return unit returns a page including the code, the code to be executed on the client terminal, the code causing the client terminal to transmit the data transmission instruction to the server, the data transmission instruction instructing the server to transmit the specified data to the providing apparatus.

6. The providing apparatus according to claim 1, wherein

the page return unit returns a page including code to the client terminal, the code to be executed on the client terminal, the code causing the client terminal to load a script on the server while serving as the data transmission instruction, and

the data reception unit receives the data transmitted to the providing apparatus by the server that has received a request for retrieval of a script by the client terminal.

7. The providing apparatus according to claim 1, wherein

the page return unit returns a page including code to the client terminal, the code to be executed on the client terminal, the code causing the client terminal to load a script on the server, the code including an encryption key of the client terminal as a parameter of the data transmission instruction,

the data reception unit receives the encrypted data transmitted to the providing apparatus by the server that has received a request for retrieval of a script called by the client terminal, and

the transfer unit transfers the encrypted data received from the server, to the client terminal.

8. The providing apparatus according to claim 1, wherein

the page return unit returns a page including the code and second code to the client terminal, the code to be executed on the client terminal, the code causing the client terminal to transmit the data transmission instruction to the server, the second code to be executed on the client terminal, the second code instructing the client terminal to retrieve display contents of a predetermined area of the page from the providing apparatus and incorporate the retrieved display contents into the page, further comprising

a display contents creation unit for creating the display contents, the display contents including the data received from the server, wherein

upon receipt of a request for retrieval of display contents specified by the second code from the client terminal, the transfer unit returns display contents created by the display contents creation unit to the client terminal.

10. The providing apparatus of claim 1, further comprising:

a server for providing data to the providing apparatus, the server comprising;

a transmission instruction reception unit for receiving the data transmission instruction transmitted by the client terminal that has received a page from the providing apparatus, the page including the code; and
