Abstract
As the volume of electronic commerce transactions increases, the increase in exchanges with client systems places an excessive load on the entire system.
A purchasing process (STEP S108) is executed through internal processing by a client system 20 on the basis of HTML files and item information (STEPS S104, 106) downloaded from a WWW server 50. This process generates no communication whatsoever with the WWW server 50. This information is written to a temporary file (cookie). In the client system, when this file changes, a web browser screen is displayed or updated in accordance with the content of the file. Thus, a proper display reflecting, for example, selection of more than one unit of a given item, can be generated without communicating with the server system.
