Each application filter must implement the IFWXSessionFilter interface. The interface is implemented by each session filter object. 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.
A session-filter object is attached to a user session when the Firewall service calls the IFWXFilter::AttachToSession method.
|QueryInterface||Returns pointers to supported interfaces.|
|AddRef||Increments the reference count.|
|Release||Decrements the reference count.|
|FirewallEventHandler||Sink for Firewall service events.|
|Detach||Called by the Firewall service when the session is shutting down.|
This interface is implemented by the application filter.
