ISAPI Extensions

ISAPI Extensions are specialized programs that run within the Internet Server Application Programming Interface (ISAPI) environment of web servers like Internet Information Services (IIS). They enable the server to handle complex or custom tasks directly, improving performance by processing requests more efficiently than traditional methods. Essentially, they are modules written to extend the server's capabilities, such as managing user authentication, serving dynamic content, or handling specific protocols. By integrating as ISAPI Extensions, these applications can interact closely with the web server, providing faster and more customized responses to user requests.
