  First, according to the conventional page-based paging technique, a user requests a specific web page from the web server 120 using the user terminal device 110, and the web server 120 correspondingly receives a request from the database 130. Data is read to generate HTML constituting the specific web page, which is transmitted to the user terminal device 110 and displayed via a web browser (not shown). However, according to such a page-based paging technique, it is not a method of displaying only the data of the changed part, but a method of displaying the page itself composed of HTML, and therefore, it takes a lot of time. there were.

  As a paging technique for solving such a problem, there is a data unit paging technique. According to this, the web server 120 is changed instead of transmitting the entire web page requested by the user. Only the data corresponding to the part can be transmitted and displayed. For example, the web server 120 can transmit only the remaining data except the data common to the previously transmitted web page among the web pages requested by the user terminal device 110, thereby improving the response time. . However, even with such a data unit paging technique, there is a problem in that the time required in the process of transmitting the data still exists.

  Meanwhile, as another example of the conventional paging technique, the web page data requested in the past is stored in the user terminal device 110, and thereafter, when the user requests the web page again, the data is stored in the user terminal device 110. There is a method for quickly displaying the web page using data. However, such a paging technique is limited in that the transmission time can be shortened only for web pages provided in the past.

  Therefore, there is a need for a paging technique that can dramatically reduce the time required to provide a web page.
