The FPCWebFilter object represents a single Web filter that is registered to extend the ISA Server Web proxy. Web filters are dynamic-link libraries (DLLs) that are loaded when the Web proxy is launched and stay in memory until it shuts down. After Web filters are loaded, they can be configured to receive a number of special filter-event notifications. These filter-event notifications are generated for each HTTP request that the Web proxy receives and for each response returned by an external Web server through the Web proxy.
In Enterprise Edition, the Web filters that are installed on an ISA Server computer are specified by including references to the applicable FPCWebFilter objects in the FPCRefs collection held in the InstalledWebFilters property of the FPCServer object.

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 an object's data to and importing it from an XML document.
The FPCWebFilter object does not define any methods.
The FPCWebFilter object has the following properties.
|Description||Gets or sets the vendor-supplied description of the Web filter.|
|Enabled||Gets or sets a Boolean value that indicates whether the Web filter is enabled.|
|FilterDirection||Gets a value from the FpcFilterDirection enumerated type that indicates whether the Web filter is invoked in the forward proxy scenario, in the reverse proxy scenario, or in both scenarios.|
|Guid||Gets the vendor-supplied globally unique identifier (GUID) of the Web filter.|
|Name||Gets or sets the vendor-supplied name of the Web filter.|
|Order||Gets the ordinal position of the Web filter in the list of Web filters, which establishes the order in which Web filters of the same priority receive data.|
|Priority||Gets or sets a value from the FpcFilterPriority enumerated type that specifies the priority of the Web filter.|
|RelativePath||Gets or sets the path to the dynamic-link library (DLL) for the Web filter relative to the ISA Server installation directory.|
|Vendor||Gets or sets the name of the vendor that supplied the Web filter.|
|Version||Gets or sets the vendor-supplied version of the filter.|
|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.|
|Save||Writes the current values of all of the object's properties 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 object that can hold sets of custom data for extending the object.|
This object implements the IFPCWebFilter 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.|
