The FPCExtensions object provides access to all the configuration settings of the ISA Server extensions (add-ins) for an ISA Server array or enterprise. ISA Server add-ins include application filters and Web filters.
Application filters work with the Microsoft Firewall service to intercept and process data. Application filters can access the data stream or datagrams associated with a session within the Firewall service. The filters are registered with the Firewall service and act in response to events detected by the service. An application filter can perform protocol-specific or system-specific tasks, such as authentication and virus checking.
Web filters are dynamic-link libraries (DLLs) that are loaded when the Firewall service is started, and stay in memory until the service shuts down. Once loaded, Web filters can be configured to receive a number of special event notifications. These event notifications can be sent for each HTTP request that the ISA Server Web proxy receives and for each response returned through the Web proxy by an external Web server.

InheritanceThis object inherits from the FPCPersist object, which contains methods and properties related to the persistent storage of an object's data. They include methods for exporting the object's data to and importing it from an XML document.
The FPCExtensions object does not define any methods.
The FPCExtensions object has the following properties.
|ApplicationFilters||Gets an FPCApplicationFilters collection that contains the application filters registered with the Microsoft Firewall service.|
|WebFilters||Gets an FPCWebFilters collection of Web filters that are registered to extend the ISA Server Web proxy.|
|CancelWaitForChanges||Cancels the registration established by the WaitForChanges method (for use in C and C++ programming only).|
|CanImport||Returns a Boolean value that indicates whether the object's properties can be imported from the specified XML document.|
|Export||Recursively writes the stored values of all the properties of the object and its subobjects to the specified XML document.|
|ExportToFile||Recursively writes the stored values of all the properties of the object and its subobjects to the specified XML file.|
|GetServiceRestartMask||Retrieves a 32-bit bitmask of the FpcServices enumerated type that specifies which services need to be restarted for currently unsaved changes to take effect.|
|Import||Recursively copies the values of all the properties of the object and of its subobjects from the specified XML document to persistent storage.|
|ImportFromFile||Recursively copies the values of all the properties of the object and of its subobjects from the specified XML file to persistent storage.|
|LoadDocProperties||Provides the XML document's properties so that you can know what information can be imported from the document.|
|Refresh||Recursively reads the values of all the properties of the object and of its subobjects from persistent storage, overwriting any changes that have not been saved.|
|Save||Recursively writes the current values of all the properties of the object and its subobjects to persistent storage.|
|WaitForChanges||Registers to wait for an event indicating that the contents of the object have changed (for use in C and C++ programming only).|
|PersistentName||Gets the persistent name of the object. The persistent name of an object is a name that is unique for the object at the respective level of the COM object hierarchy.|
|VendorParametersSets||Gets an FPCVendorParametersSets collection that can hold sets of custom data for extending the object.|
This object implements the IFPCExtensions interface.
|Client||Requires Windows XP.|
|Server||Requires Windows Server 2003. Requires Windows Server 2003 or Windows 2000 for ISA Server 2004 Standard Edition.|
|Version||Requires Internet Security and Acceleration (ISA) Server 2006 or ISA Server 2004.|
