FPCApplicationFilter

Internet Security and Acceleration Server 2004/2006 SDK

The FPCApplicationFilter object represents a single application filter. 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 checking for viruses.

The application filters that are associated with a protocol are specified by including references to the applicable FPCApplicationFilter objects in the FPCRefs collection held in the ApplicationFilters property of the FPCProtocolDefinition object.

In Enterprise Edition, the application filters that are installed on an ISA Server computer are specified by including references to the applicable FPCApplicationFilter objects in the FPCRefs collection held in the InstalledApplicationFilters property of the FPCServer object.

The FPCApplicationFilter object is an element of an FPCApplicationFilters collection, and a new object representing an application filter can be created by calling the Add method of this collection.

Methods Inherited from FPCPersist

Name	Description
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	Writes the stored values of all of the object's properties to the specified XML document.
ExportToFile	Writes the stored values of all of the object's properties 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	Copies the values of all of the object's properties from the specified XML document to persistent storage.
ImportFromFile	Copies the values of all of the object's properties 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	Reads the values of all of the object's properties from persistent storage, overwriting any changes that have not been saved.
