ISAPI extensions provide a means of scripting for the Web Server. ISAPI extensions are implemented as DLLs that are loaded into the same process as the Web Server.
ISAPI filters are DLLs that are loaded into the process of the Web Server when it is started, and they stay in memory until the Web Server shuts down. After they are loaded, ISAPI filters can be configured to receive a number of special filter-event notifications that occur with each HTTP request that the Web Server receives and with each response that the Web Server generates in return.
