Means 13 are to be drawn based on the drawn contents.
- the session server 2 and the log management server 12 are different servers has been described, but the session server 2 is provided with the function of the log management server It goes without saying that a functionally integrated server may be used.
- Synchronization program 1 as described above has a remarkable effect when it is used for an input agency service or support on the network 3, but especially in the case of an online shopping input agency service,
- a protocol such as Secure Sockets Layer (SSL) may be used.
- SSL Secure Sockets Layer
- the content requires confidentiality such that the content must be encrypted during communication on the network 3.
- the host-side computer terminal 4 can directly communicate with a web server or the like by SSL, but the remote-side computer terminal 4 obtains the content from the storage unit 8 of the host-side computer terminal 4, so the SSL-based communication is used. Cannot be performed.
- the session server 2 detects that an application has been made for the product application from the remote-side support terminal 4 of the support center. In this case, by displaying a warning on the computer terminal 4 of the user on the host side, it is possible to prevent the support center from making a product application or the like without permission. In this case, the user may approve the warning by adopting a form in which the user approves the warning.

- the program itself read from the storage medium implements the functions of the above-described embodiment, and the storage medium storing the program naturally constitutes the present invention.
- this program for example, a magnetic disk, a hard disk, an optical disk, a magneto-optical disk, a magnetic tape, a nonvolatile memory card, or the like can be used.
- this program It may be a carrier wave provided through a wireless communication line, or any device or computer recording this program.
- the content can be synchronized between the computer terminals without storing the content on the server as in a conventional collaboration server.
- the session server according to the present invention merely mediates a session without storing the content. Therefore, even if a large number of users synchronize the content in parallel, the conventional collaboration server is used. As described above, a heavy load does not occur, and the session server itself does not need to have high performance, so that the system construction can be made inexpensive.
- the content itself was held on the collaboration server Therefore, the computer terminals that perform the synchronization are limited to the subordinate of the collaboration server.
- the session server itself exists only for managing the session, and routing between servers can be easily realized. Therefore, it is possible to synchronize any person on the Internet without being limited to a specific collaboration server.
- the content at the time of synchronization is stored as a log, and the content is transmitted from the session server to the other computer terminal. Even without access, the content can be viewed on the other computer terminal.
