I've just seen this example.

[Server] Guess My Number example

The purpose of this example is to demonstrate how you can interact with the server through ajax requests. The server chooses a number and the user needs to guess the number. Whenever the user presses on the Guess button a request is sent to the Guess handler: Sub Handle(req As...

Am I right to assume that the way to handle user sessions also with BANano is

Sub Handle(req As ServletRequest, resp As ServletResponse)
   If req.GetSession.HasAttribute("myNumber") = False Then
     req.GetSession.SetAttribute("myNumber", Rnd(0, 101)) '<-- store the number in the user session
   End If
   Dim myNumber As Int = req.GetSession.GetAttribute("myNumber")
   Dim n As String = req.GetParameter("number")
   If IsNumber(n) = False Then
     resp.Write("Please enter a valid number.")
   Else
     If n > myNumber Then
       resp.Write("My number is smaller.")
     Else If n < myNumber Then
       resp.Write("My number is larger.")
     Else
       resp.Write("Well done!!!")
     End If
   End If
End Sub

As per this example? and you dont need to have these on your handler page

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)

Thanks

In a websocket class, use ws.Session.

and you dont need to have these on your handler page

In a WebSocket class (bi-directional) yes, needed. In a Handler class it has nothing to do with websockets, but is only one direction (browser -> server)
