Timeout in Forms Authentication

There are two things

1. FormsAuthentication.SetAuthCookie("userId",true);

this means the cookie will now be permanently stored in your browser until you delete it explicitly.

 

2.  

here, the timeout means the cookie will be of no use after 30 minutes even if you have a permanent cookie stored in the browser. and after login, the cookie which is stored in the browser will be replaced with the new one.

 

for testing, after login set the remember me to true means  SetAuthCookie("userId", true) and close the browser but if you open the application within 30 minutes then you won't need to log in again.
