Cookie setzten :

procedure TForm1.Button1Click(Sender: TObject);
begin
  SetCookie('myCookie');
end;

Cookie löschen :

procedure TForm1.Button2Click(Sender: TObject);
var sString: String;
begin
  sString := 'myCookie';
  //sString := GetCookie;  // HIER FÜR LOKALE CACHE SUCHE 
   if(sString <> '') then begin
    try
      ShowMessage(sString);
    except
   on E: Exception do ShowMessage(E.Message+' '+IntToStr(E.HelpContext));
   end;
  end;
