3.3.4 Higher-Layer Triggered Events
Events can be triggered from the higher layer on the server to disconnect the SSTP connection.

The management layer can issue disconnection requests based on an administrator command or any other local policies. <13> Server disconnect processing is the same as the client-side disconnect processing (section 188.8.131.52).
