login redirect problem

I have 2 controllers, each has his login page.

At the 2nd, ‘support’ controller after I log-in and logout, when I re-login I am redirecting at site controller.

How can I redirect at support controller and not at site controller?

Please post an example to understand it a little more…

So I login at support,do something and logout.

Now I am at login page of support controller.

So I login again and I am redirecting at site controller.

I want to be at support controller

I wrote

class SupportController extends CController {....

public function __construct() {
