Abstract

PROBLEM TO BE SOLVED: To allow a client terminal to fast read an HTML(Hyper Text Markup Language) document by preparing the HTML document with a small amount of data capacity when a load is applied to a network. SOLUTION: A WWW server 13 counts the number of accessing times made by the client terminal. When the number of accesses within a prescribe period of time surpasses the maximum access number when the client terminal makes an access, a CGI(Common Gateway Interface) 173 prepares an HTML document without fetching a Java applet 175. When the number of accesses is not larger than the maximum access number, a CGI 172 fetches the Java applet 175, prepares an HTML document and transmits the data so that the client terminal can read the data.
