How to perform persistent connection using WebSocket and a Delphi Socket server?

I'm trying to create a communication via WebSocket with a Delphi socket server,

1st Step, readystate 0 - Server receives the WebSocket header.

Step 2, readystate 3 - Already going offline.

Javascript:

var host = 'ws://10.1.1.10:8100'; // SET THIS TO YOUR SERVER
socketWebservice = new WebSocket(host);

socketWebservice.onopen = function(msg) {
  socketWebservice.send('LOGON');
  alert('entrou');
  //setIntSocketSend = setInterval('contSendSocket()', 119000); //confere o Login a cada 4m:58s
};
socketWebservice.onmessage = function(msg) {
  on_socket_get(msg.data);
};
socketWebservice.onclose = function(msg) {
  //            clearInterval(setIntSocketSend);
  console.log(msg);
};

Delphi uses the TServerSocket component.

Server Code:

unit uServidor;

interface

uses System.Win.ScktComp, Vcl.StdCtrls, Vcl.Controls, System.Classes, Vcl.Forms,
     System.SysUtils;

type
  TForm1 = class(TForm)
    ServerSocket1: TServerSocket;
    ListBox1: TListBox;
    Label1: TLabel;
    Button1: TButton;
    EdtPorta: TEdit;
    Label2: TLabel;
    BtnConectar: TButton;
    ckTodos: TCheckBox;
    EdtMensagem: TMemo;
    procedure BtnConectarClick(Sender: TObject);
    procedure ServerSocket1ClientConnect(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure Button1Click(Sender: TObject);
    procedure ServerSocket1ClientRead(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure ServerSocket1ClientDisconnect(Sender: TObject;
      Socket: TCustomWinSocket);
  private
    procedure Reconectar;
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.BtnConectarClick(Sender: TObject);
begin
  ServerSocket1.Port   := StrToInt(EdtPorta.Text);
  try
    ServerSocket1.Active := true;
    BtnConectar.Caption  := 'Conectado';
    BtnConectar.Enabled  := false;
  except
    raise;
  end;
end;

procedure TForm1.ServerSocket1ClientConnect(Sender: TObject;
  Socket: TCustomWinSocket);
var
  I : Integer;
begin
  ListBox1.Items.Clear;
  for I := 0 to Pred(ServerSocket1.Socket.ActiveConnections) do
    ListBox1.Items.Add('['+ServerSocket1.Socket.Connections[I].RemoteAddress+']');
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  I : Integer;
begin
  if ckTodos.Checked then
    for I := 0 to Pred(ListBox1.Items.Count) do
      ServerSocket1.Socket.Connections[I].SendText(EdtMensagem.Lines.Text)
  else
    ServerSocket1.Socket.Connections[ListBox1.ItemIndex].SendText(EdtMensagem.Lines.Text);
end;

procedure TForm1.ServerSocket1ClientRead(Sender: TObject;
  Socket: TCustomWinSocket);
begin
  EdtMensagem.TEXT := Socket.ReceiveText;
end;

procedure TForm1.Reconectar;
begin
  ServerSocket1.Active := false;
  ServerSocket1.Active := true;
end;

procedure TForm1.ServerSocket1ClientDisconnect(Sender: TObject;
  Socket: TCustomWinSocket);
var
  I : Integer;
  Endereco : String;
begin
  for I := 0 to Pred(ListBox1.Items.Count) do
  begin
    Endereco := '['+Socket.RemoteAddress+']';
    if Endereco = ListBox1.Items.Strings[I] then
    begin
      ListBox1.Items.Strings[I] := ListBox1.Items.Strings[I] + ' - DESCONECTADO';
      break;
    end;
  end;
end;

end.
