The TCP connection between a client and the server has been broken. If the client automatically and repeatedly attempts to re-establish the connection, the server can raise this event multiple times for a single client. To determine when a client session has ended, you can use the WMS_EVENT_END_USER_SESSION event notice. You can use the HRESULT from the WMS_EVENT structure to determine whether the connection attempt succeeded.
Server-level plug-ins receive this event; however, publishing-point-level plug-ins will not. For more information, see Event Level.
