As the number of users increases, it is desired to provide a system for reducing traffic when accessing a Web server from a terminal.

  Conventionally, as this type of system, those described in Patent Document 1, Patent Document 2, and Patent Document 3 are known. First, the “client / server database” described in Patent Document 1 provides a file equivalent to the server for each client, provides a data update history for each client to the server, and when each client updates the file, The same update contents are reflected on the files of each client connected to the network, and when each client not connected to the network connects again, the client's file is updated based on the data update history since the last access. Reflect the updated contents in the file. As a result, when a file is referred to by each client, the network is not used at all, so that traffic can be reduced.

  Next, the “Internet homepage management system” described in Patent Document 2 acquires a cached homepage revision and notifies the web server when the browser accesses the homepage. The history file acquired with the revision of the key as the key and the latest revision are transmitted to the browser, and the browser updates the cache file according to the history file received from the web server and displays the cache file. As a result, the web server transmits only the portion of the homepage that has been received by the browser in the past, so that the speed reduction due to an increase in traffic can be prevented in advance.

In addition, the “information acquisition terminal, information cache server, and information acquisition method” disclosed in Patent Document 3 indicates whether or not data is updated from the information acquisition terminal to the information provision server every predetermined time after data is acquired from the information provision server. If the response is that there is data update, the data transmission is requested. Thus, the updated data can be requested even after the acquired data is updated on the information providing server side.
In addition, an information cache server is connected between the information acquisition terminal and the information providing server, an inquiry about whether or not there is data update is transmitted to the information providing server at a predetermined time, and if the response is data update, Is registered in the cache disk, and in response to a data request from the information acquisition terminal, the data registered in the cache disk is transmitted. As a result, the data from the information providing server is stored in the cache disk in a time zone with a small amount of traffic, so that it is possible to reduce traffic in a time zone in which access is concentrated.
