Connection

​
The first thing an APP needs to do is to open a WebSocket connection with a HAS server. Once connected, the HAS will send a connected message with additional information.
{ 
    cmd: "connected", 
    timeout: number,
    version: string,
    protocol: number
}
Properties
timeout: delay (in seconds) before the server considers requests to be expired. The default value is 60 seconds.
version: HAS code version
protocol: HAS protocol version
An application should decline to connect to a HAS infrastructure whose protocol version is greater than the one it supports.
