Connection specific AppendShutdownHandler

[Anonymous]

Hi,
I’m currently trying to create a sort of forwarder which listens on a port, then receive a certain packet which will tell him where to redirect next pacekts coming from the same client.

Example:
CLIENT tell GATEWAY that he needs to get to SERVER:serverport
GATEWAY creates a connection to SERVER:serverport
CLIENT sends packets to GATEWAY which sends them to SERVER
SERVER sends back a response, which goes through the GATEWAY to the CLIENT.

I had it working with Net.Sockets and I’m now changing to NetworkComms.

The problem I’m facing is that when a connection from Gateway (client) to Server (listening server) is closed, the Gateway trigger the global callbacks for connection/disconnection:

NetworkComms.AppendGlobalConnectionCloseHandler(ClientDisconnected);
NetworkComms.AppendGlobalConnectionEstablishHandler(ClientConnected);

Those callbacks are supposed to be only called when a client connect or disconnect on the Gateway

This is the code i’m currently using to start the listener.

NetworkComms.DefaultSendReceiveOptions = new SendReceiveOptions<ProtobufSerializer, , LZMACompressor>();
NetworkComms.DefaultSendReceiveOptions.IncludePacketConstructionTime = NetworkComms.DefaultSendReceiveOptions.ReceiveHandlePriority = QueueItemPriority.AboveNormal;
NetworkComms.AppendGlobalConnectionCloseHandler(SessionClosed);
NetworkComms.AppendGlobalConnectionEstablishHandler(NewSessionConnected);
NetworkComms.AppendGlobalIncomingPacketHandler<string>("ECHO", SocketCommands.HandleIncomingECHOPacket);
Connection.StartListening(ConnectionType.TCP, new IPEndPoint(IPAddress.Any, 10000));

I suppose this is like a “global” way of starting It?
How do I start one then add those Connected/Disconnected handlers to just the listener?

Thanks

Create an instance of TCPConnectionListener and then use TCPConnectionListener.AppendIncomingPacketHandler.

Once configured you can provide the listener to ConnectionListeners.StartListening

Thanks for the answer,
What i already do is this:

TCPConnectionListener listener = new TCPConnectionListener(new SendReceiveOptions<ProtobufSerializer, LZMACompressor>(), ApplicationLayerProtocolStatus.Enabled, true);

NetworkComms.AppendGlobalConnectionCloseHandler(ClientDisconnected);
NetworkComms.AppendGlobalConnectionEstablishHandler(ClientConnected);

listener.AppendIncomingPacketHandler<string>("PING", HandleIncomingPINGPacket);
listener.AppendIncomingPacketHandler<string>("DEST", HandleIncomingDESTPacket);
listener.AppendIncomingPacketHandler<byte[]>("DATA", HandleIncomingDATAPacket);

Connection.StartListening(listener, new IPEndPoint(IPAddress.Any, 19000));

Basically I would like to make those ClientConnected and ClientDisconnected related to this listener, instead of make them global.
The reason why is because I got a client in the same application, and when it connects or disconnects It triggers the same methods of this listener.

I don’t think this is possible directly. There is currently no listener.AppendConnectionCloseHandler() method. One work around is to check the IP address in the global AppendGlobalConnectionEstablishHandler and then add a connection specific close handler there.
