The IFWXSessionFilter interface exposes a method that the Microsoft Firewall service can use to send notifications about events that the filter is registered to handle in a specific user session. Each user session may have a different combination of session filters attached to it. However, each session filter is attached to a single user session.
An instance of the session filter object is created for a user session when the Firewall service calls the IFWXFilter::AttachToSession method.
This is the interface typically used for attaching a data filter to a user session.
For more information about how the IFWXSessionFilter interface is used in application filters, see Filter Object Model.

interface IFWXSessionFilter : IUnknown
Every application filter must implement this interface to receive notifications for events in a user session and to react to these events.
The IFWXSessionFilter interface inherits the methods of the IUnknown interface.
In addition, IFWXSessionFilter defines the following methods.
| Method | Description |
|---|---|
|
Notifies the filter that the Microsoft Firewall service detected an event related to the user session to which the session filter is attached. |
|
|

| Server | Requires Windows Server 2008. |
|---|---|
| Version | Requires Forefront Threat Management Gateway (TMG). |
