ISAPI Filters

ISAPI Filters are software components that run on a web server, allowing customization of how the server handles requests and responses. They act as middleware, intercepting and processing data as it flows between clients and the server, enabling tasks like filtering content, logging traffic, or modifying data in real-time. Think of them as specialized filters or gatekeepers that enable administrators to enhance, monitor, or control web server behavior without altering the core server code. This makes ISAPI Filters a flexible tool for extending server functionality in a secure and efficient manner.
