FPCExtensions Object

The FPCExtensions object provides access to all the configuration settings of the Forefront TMG extensions (add-ins) for a Forefront TMG array or enterprise. Forefront TMG 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 Forefront TMG Web proxy receives and for each response returned through the Web proxy by an external Web server.

This object is accessed through the Extensions property of an FPCArray object.

When an enterprise with central array management is deployed, this object is also accessed through the Extensions property of the FPCEnterprise object to access the network configuration settings for the enterprise.

Inheritance

This 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.

Methods

The FPCExtensions object does not define any methods.

Properties

The FPCExtensions object defines the following properties.

Property	Description
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 Forefront TMG Web proxy.

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	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).

Properties Inherited from FPCPersist

Name	Description
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.
VendorParameterSets	Gets an FPCVendorParametersSets collection that can hold sets of custom data for extending the object.
