If you are an ISP, you can specify how users sign up with your service and connect to the Internet.
Internet Sign-up ServerCGI is a specification for programs than run on an Internet server.To set up a CGI program, you'll need to ensure it can run at your site, place it in the proper directory (frequently the Cgi-bin directory), add a .cgi extension if necessary, and set up the proper permissions on the program and associated files.
You can use Microsoft Active Server Pages (ASP) to embed scripts within your HTML pages to create dynamic, interactive content for your Web site. In the past, scripts written in the popular scripting languages, such as Visual Basic Scripting Edition (VB Script) JavaScript, and JScript, have been processed by Web browsers that support the language in which the script was written. Active Server Pages enables your Web server to process script. Any browser that can contact your Web server, regardless of its support for scripting, can work with ASP and the dynamic output. ASP is supported on Microsoft Internet Information Server 3.0 or later.
