IIS (Internet Information Services) is a web server for hosting websites and applications on Windows. When a client requests an ASP file, IIS processes the request by invoking the ASP engine, which interprets the embedded VBScript or JScript code in the file. The server executes the script, interacts with any databases or resources, and generates HTML content, which is then sent back to the client's browser. This dynamic content generation allows for interactive and responsive web applications.
