A specification for a dynamically created Web page with an .ASP extension that contain either Visual Basic or JScript code. When a browser requests an ASP page, the Web server generates a page with HTML code and sends it back to the browser. ASP pages are similar to CGI scripts, but they enable Visual Basic programmers to work with familiar tools. ASP is only available on NT servers.
Active Server Pages is a server-side scripting technology developed by Microsoft. With ASP you can create dynamic web pages by putting script code inside your HTML pages. The code is executed by the web server before the page is returned to the browser.
