IFWXSessionFilter interface

Applies to: desktop apps only

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.

For more information about implementing the IFWXSessionFilter interface, see Implementing a Session Filter Object.

Every application filter must implement this interface to receive notifications for events in a user session and to react to these events.
