how to use enableAutoLogin and where did it save cookie?

Hi everyone, i got a problem.

If enableAutoLogin = true, Yii will store cookie when user login in.

But i cannot find cookie through my browser.

Where does yii store the cookie ?

Or i lost other params config to let autologin funciton work?

Please give me some suggestions, leave it under my topic, or send to my email 343206609@qq.com.

Thank You !
