Internet Server Application Programming Interface (ISAPI)

The Internet Server Application Programming Interface (ISAPI) is a set of tools that allows web developers to create programs that work with Microsoft Internet Information Services (IIS), a popular web server software. ISAPI enables developers to build dynamic web applications by processing requests from users, generating responses (like web pages), and handling data efficiently. It supports features like custom file handling and enhances web server performance. Essentially, ISAPI helps programmers extend the capabilities of the web server to deliver dynamic and interactive content to users online.
