Microsoft Internet Security and Acceleration Server 2000


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.
