Abstract
This article describes the Internet survey using CGI (Common Gateway Interface). After explaining the operation of CGI, we will introduce its application examples and a tool for creating a system using CGI. It is difficult to use casually because web pages including a form tag, CGI programs and a server on which the CGI programs run have to be prepared. However, its high degree of freedom and various applications have advantages. As a concrete example, we describe the electronic voting system of a small academic society that the author has operated for nearly 20 years.
