1. Why aren't you using Sleep(3000)?
2. Why aren't you using jServer to build a real http server?

You need to update to the latest version.

End Sub

Sub AppStart (Args() As String)
    plc.Initialize
    '
    srvr.Initialize("srvr")
    srvr.Port = 8010
    srvr.AddHandler("/put", "PutHandler", False)
    srvr.AddHandler("/get", "GetHandler", False)
    srvr.Start
    Log($"Server started by ${srvr.Port}"$)
   
    timer1.Initialize("timer1",250)
