NOTE: This event is now obsolete.
OnShutdownRequest has been superseded by OnDisconnect.
This event has been superseded by the OnDisconnect event, and is retained only for backwards compatibility with existing plugins. New or updated plugins should use OnDisconnect instead. This event is dispatched when the connection with Iguana is closed for any reason other than the plugin calling disconnect (or destroying the message processor object). Typically, this event is received when the Iguana channel is stopping, however, it may also be received upon disconnection due to network failures or other error conditions. Note that exceptions can never be thrown out of this handler. Any exceptions thrown will result in the client executable aborting. It is recommended that logging or the handling of exceptions is performed in the handler.
