Virtual Common Gateway Interface Program on the Network Using the Destination Addressing Control System Scheme

In the world of the Internet, Web Servers such as Apache and Internet Information Server (IIS) were developed to exchange information among client computers having different Operation System. They have only the function of displaying static information such as HTML file and image file into the Web Browser. This problem was solved by use of a Common Gateway Interface (CGI) program. As the CGI programs, there are bulletin board system and access counter, Blog system or Wiki. However, in these programs, there are many CGI programs which don´t have user authentication mechanism and access control mechanism the user group. That is, these CGI programs have the problem that user can access it freely only by getting the URL to access it. In this paper, the virtual use method of this kind of CGI program having the effect that is equal to add the user authentication mechanism and access control mechanism is proposed. This virtual use method is realized in the case of introducing the Destination Addressing Control System (DACS) Scheme as a network management scheme, which is a kind of Policy Based Network Management Scheme (PBNM) that we have been proposed before. As the result, this kind of the CGI program opened to Internet can be used in the organization in the state of having the almost same functions.
