[Catalyst] Ajax and redirect

[fayland]

Hi, all.
It seems that redirect doesn't work with Ajax, the reason might be Ajax 
just update a "div" and div cann't recieve the header: Location stuff. 
There is any way to get out? use "meta refresh" instead "redirect"?

my code is as follows:

Controller:

sub vote : Global {
    my ( $self, $c ) = @_;

    $c->res->redirect('/login') unless ($c->user_exists);

and TT files:

var url = '/vote';
var myAjax = new Ajax.Updater('vote_result', url, {method: 'get', 
parameters: pars});

<div id='vote_result'></div>

Any tips are greatly appreciated, thanks very much.
