Description of the invention G) Inventive Range® The present invention outlines the communication between a user computer and a server computer on a computer network (such as the Internet). More specifically, the present invention helps to update information in a web page loaded on a user's computer. BACKGROUND OF THE INVENTION Typically, a browser program (such as Microsoft's Internet Explorer or Netscape's navigator) is used to download a web page from a server computer to a user's user's computer via the Internet. on. A one-page web page typically contains various components such as graphic objects, data fields, and data. For example, in the case of a financial information network portal, the webpage can contain stock quotes and currency exchange information that is prone to continuous fluctuations. After the user has performed an initial download operation, a common method for updating the webpage to obtain the updated information will utilize the browser's,,,,,, and buttons. By pressing the update button again, the entire web page is completely downloaded from the server computer, including all graphical objects that may not have changed. Therefore, in order to obtain little updated data, a large amount of data needs to be transferred on the Internet, and the browser needs to retranslate the large amount of data. This is for efficiency in terms of the response time experienced by the vhai user, as well as the communication link that should be used to connect the server and the user's computer to the Internet. Microsoft Internet Explorer has a dynamic X-control that addresses the aforementioned disadvantages, such as the prior art, by allowing dynamic data updates. Other browsers cannot take advantage of this feature. Learn about other ways to update your website from this prior art. Standard for this paper 535071 A7 B7 V.
