input->set_cookie or setcookie not work

[eluser]helloworld7[/eluser]
Hi. Thank you. Almost have this figure it out. I did the test you gave me and it worked. Then I tried to move the bar function to my controller B and didn't get the same result as before but I think I may know what's the issue.

I had controller A as /login then controller B as /myaccount/home (I actually have a /myaccount/ dir).

Is it because it's different path? The cookie is only available only for /login and ./*?

But method 1 I had ‘domain’ => ‘.somedomain.com’ on cookie, is that mean it should work for all path for that domain?

If that's the issue. How do I set my cookie so that I can retrieve it from all controller(even with different directory)?
