When the web page is moved to the child site of the information site with the detail button 10 pressed, its web page 28 is provided with a return button 29 and the web page can be returned to the original parent site with the return button 29 pressed. When data for explanation of the child site are called, it is checked whether or not a link with another site other than the parent site is described and when so, it is made ineffectively to disable a link to the other site. |
