IIS 6.0 F1: Web Site Properties - ISAPI Filters Tab
Applies To: Windows Server 2008 R2
Use this tab to set options for ISAPI filters. An ISAPI filter is a program that responds to events during the processing of an HTTP request. The table lists each filter's status (which can be enabled or disabled), file name, and priority for loading into memory. You can change the execution order of filters only with the same priority.
If you have added or changed a filter at the global level, you must restart Internet Information Services (IIS) to load the new filter. If you have added or changed a filter at the Web site level, the filter is not loaded until a request is made to the Web site.
