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.
