Active Server Pages (ASP) is a Microsoft technology for generating dynamic HTML content. Dynamic content is content that changes based on user input and on the instructions you provide in the ASP code. ASP is ideal for creating web pages customized for different types of users, as well as for web sites that allow a user to browse and perform actions on records in a database.

ASP is not a standalone technology; rather, ASP files are essentially HTML files with server scripts included to create and handle dynamic content. You use a scripting language, such as VBScript (the default scripting language) or JavaScript, to write the functions and procedures that the application (web site) will use.
