Answer 1

Something like this:

// current array index
private var connIndex:int = 0;

public function connect():void
{
    var mySocketURI:SocketUri = urisToTry[connIndex];

    // do your connection here
}

private function onConnectionLost():void
{
    // increase index and check if it is within array length
    if(connIndex >= urisToTry.length -1)
        connIndex = 0;
    else
        connIndex++;

    connect();
}
