Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web page browsing method, a client of a web page browsing system, and a web page browsing program capable of browsing a web page while reducing network traffic.

[0002]

2. Description of the Related Art Conventionally, as a method of reducing network traffic when a user browses a web page via a network, there has been a method of using a client cache or a proxy cache.

According to the method using the client cache, when a web page is browsed, the data downloaded from the web server by the user through the network is temporarily stored in the client computer, and the same web page is requested to browse again. In this case, since the cache file already stored in the client computer is browsed without re-acquiring data from the web server, the display speed of the web page can be increased.

On the other hand, the proxy cache is usually arranged at the end of the network (in-house gateway etc.), and many users connected to the proxy cache can efficiently access various documents on the network such as the Internet. To do so.

In the method of using the proxy cache, the user first accesses the proxy server without directly accessing the original web server that desires to browse the web page. Then, the accessed proxy server accesses the web page requested by the user, receives the web page data, further transmits the received web page data to the user, and transmits the web page data to the disk of the proxy server ( Proxy cache). When the same web page is accessed after the reception, the web page data stored in the cache of the proxy server is used for the response to this access. By using the proxy cache in this way, the speed of reading and displaying web pages can be increased. Also, because you will not access the same web page multiple times,
Internet resources can be saved.

As described above, by using the conventional techniques such as the client cache and the proxy cache, the reading speed and the display speed of the web page are increased, so that the time required for the user to display the desired web page is shortened. I was able to.

[0007]

However, according to the above-mentioned conventional technique, new data is not updated at any time because the web page data is not newly acquired from the client computer to the web server. Therefore, when browsing a web page whose data is frequently updated, the user displays old web page data before the update. Here, when the old web page data before update is displayed in this way, the user can go to the web server to obtain the latest web page data by clicking the update button of the browser. However, when this update button is clicked to acquire data, all the data of the web page, that is, the same data as before, which has not been updated together with the updated latest data, is requested to be acquired by the web server. As a result, there has been a problem that the display time of the web page is delayed.

Therefore, an object of the present invention is to provide a web page browsing method, a client of the web page browsing system, and a web page browsing program capable of reducing network traffic and rapidly performing display processing of the web page. Is.
