Understanding connection flow

The client connects to the server, and the server calls onAppStart when the application

instance is loaded (if the application is already running,

onAppStart is not called). Next, the

server-side

onConnect handler is invoked with a newly created Client object. The logic in this

method determines whether to accept or reject the connection. On the client side, the

onStatus handler is called to report whether the connection was accepted or rejected. When

the client closes the connection, the server-side

onDisconnect handler is called. When the

application is unloaded,

onAppStop is invoked.

To accept the connection in the

onConnect handler, return true or call

application.acceptConnection(); to reject the connection, return false or call

application.rejectConnection(). If true or false are not returned in the onConnect

handler, clients remain pending until

acceptConnection() or rejectConnection() is

called.

Connection flow

NOTE

Only the client application can initiate a communication session. Both the client and the

server send and receive status messages, open and close streams, save and share data,

and end the network connection.
