ISAPI filter

World-Wide Web A replaceable DLL which the server calls

whenever there is an HTTP request. When the filter is first

loaded, it communicates to the server what sort of

notifications will be accepted. After that, whenever a

selected event occurs, the filter is called to process the

event.

Example applications of ISAPI filters include custom

authentication schemes, compression, encryption,

logging, traffic analysis or other request analyses.
