Если все правильно понял то, как то так получается?

Код не авторский, собран из выдачи в гугле + свои додумки.
В JS не силен, подскажите такая конструкция будет работать?

function set_cookie ( name, value, exp_y, exp_m, exp_d, path, domain, secure )
{
  var cookie_string = name + "=" + escape ( value );
  if ( exp_y )
  {
    var expires = new Date ( exp_y, exp_m, exp_d );
    cookie_string += "; expires=" + expires.toGMTString();
  }
  if ( path )
        cookie_string += "; path=" + escape ( path );
  if ( domain )
        cookie_string += "; domain=" + escape ( domain );
  if ( secure )
        cookie_string += "; secure";
  document.cookie = cookie_string;
}
function get_cookie ( cookie_name )
{
  var results = document.cookie.match ( '(^|;) ?' + cookie_name + '=([^;]*)(;|$)' );
  if ( results )
    return ( unescape ( results[2] ) );
  else
    return null;
}
    var s=location.href;
    var st = s.substr(s.lastIndexOf("/")+1);
    var current_date = new Date();
    var cookie_year = current_date.getFullYear ( ) + 1;
    var cookie_month = current_date.getMonth ( );
    var cookie_day = current_date.getDate ( );
   if ( (! get_cookie ( "cookieName" )) && ( st  == "index.html")  )
   {
    set_cookie ( "cookieName", "1", cookie_year, cookie_month, cookie_day );
   }
   if ( ( st  == "1.html")  ){
    set_cookie ( "cookieName", "2", cookie_year, cookie_month, cookie_day );
   }
   if ( ( st  == "2.html")  ){
    set_cookie ( "cookieName", "3", cookie_year, cookie_month, cookie_day );
   }
	var check = get_cookie ( "cookieName" );

if ( (check == "1") && !( st  == "index.html") ){
	top.location = "index.html";
	}
if ( (check == "2") && !( st  == "1.html") ){
	top.location = "1.html";
	}
