program provided in a computer such as a server is invoked at the time of contentchange, and records a change history record in a content change management table.When a requested content is not found in a database, a WWW server program invokes acontent change reference program, which refers to the content change managementtable, converts a specified URL into a URL after move, and returns the URL after move tothe WWW server program. If the specified URL has been deleted, the content changereference program returns a URL of content, which displays a deletion message, to theWWW server program. In the case of a computer like a proxy server interposed betweena client computer and a server computer, when receiving a content request from theclient, a content change management table obtained from the WWW server is referredto. After that, a specified URL is converted into a URL after move. Then, the URL aftermove is transmitted to the WWW server.
