IE8 and session problem

[eluser]Ajaxian64[/eluser]
Hi,

I use ci session with database storage.
I use cisession name instead of ci_session

Whenever a user connect I create a session.
Then he chooses one of two possible roles 'client' and 'invite'

I would like to make impossible to load http://mysite/users/connect when a session is running.

Then in my controller "users" I do this

Code:

private function _verif_session_and_redirect() {
        if($this->session->userdata('user_id') != FALSE) {
            $role = $this->session->userdata('role') ;
            if ($role == 'client')
                redirect('clients/home');
            else if ($role == 'invite')
                    redirect('invites/home');
            else {
                redirect('site');
            }

        }
    }

    function connection() {
    
        $this->_verif_session_and_redirect() ;

                // etc ..
         }

I test with Firefox => it works I have the redirection to clients/home (if I'm a client)
I test with Chrome => it works
I test with Safari => it works
I test with IE8 => Don't work I have the connection form....
Do you know why ? If there a bug ?
Thanks

In fact If I use trace. When I load http://mysite/users/connect on IE8, the session is not recognize.
Then It displays the form view
But when I do a refresh via F5, then It does not reload the form but seems to recognize the session and THEN redirect me to the right place http://mysite/clients/home
And then, if he try from this point to reload http://mysite/users/connect then IE8 does the job as it was intended from the firts time (redirect to http://mysite/clients/home)

Always KO
But:
In the view that displays the http://mysite/clients/home I have had (just for test) this:

Code:

<?php echo anchor('users/connection','connection'); ?>

Then When I click on it and due to the fact that I have a session running, then IE8 does the right stuff and redirect me to http://mysite/clients/home.

The problem is that the first attempt to load from http://mysite/clients/home, the url http://mysite/users/connection by writing this directly on the browser (I don't know the word in english for this area on which you enter directly the url) then It doesn't work with IE8

My problem is far more important than described previously.
I set up the code on a real server (previously I was on localhost)

I can connect to my site with Chrome and Opera. But for IE and FireFox it seems there is a problem of session.

For real server I don't what to put on those following set up:

Code:

$config['cookie_prefix']    = "";
$config['cookie_domain']    = "";
$config['cookie_path']        = "/";

$config['cookie_prefix'] => No need (I hope)
$config['cookie_domain'] = 'mysite.com' Is it right ?
But entirely lost on $config['cookie_path'] = "/"; I really don't know how to set up this ...

Some help would be very appreciate ...

Bit of a bump, but this solution also worked for me! (Also removed _ from my session name)
