The Clientcloses the connection by sending a CloseSecureChannelrequest and closing the socket gracefully. When the Serverreceives this Message,it shall release all resources allocated for the channel. The body of the CloseSecureChannelrequest is empty. The Serverdoes not send a CloseSecureChannel response.
The Serverapplication does not do any processing when the SecureChannelis closed; however, the Stackshall provide notifications to the Serverapplication whenever a CloseSecureChannelrequest is received or when the Stackcleans up an abandoned SecureChannel.
