I use post_controller_constructor to check session if the user can access the system.
But I have to input the user name and password twice to login.
The first time I login, it will redirect to the login page to let me input the info again.
But if I login out, I'm sure the session is clean, and I only need to login once.
Also I have to point that, one weeks ago, the IE works well(login once), when I use Firefox, I need to login twice.
But now, the firefox works well, I have to login twicw under IE...
who can help me?...
I feel I was dying, poor system....
