Re-loading library?

[eluser]guidorossi[/eluser]
Hi!

I'm trying to make my own auth library with all the things I want and removing the things I don't want or need...

I based my code taking things from some others libraries like ion and wolf...

I'm having some trouble with the "remember me" option...

Basically I've got on my config.php:

Code:

$config['sess_expire_on_close'] = TRUE;

Then on my auth library I load the session library on the controller, but on my log_in() function of the auth library I want to make the "sess_expire_on_close" FALSE if "rememberme" is TRUE:

Code:

if ($remember == TRUE)
{
   $config['sess_expire_on_close'] = FALSE;
   $this->ci->load->library('session', $config);
   $this->remember_me($user->id);
}

but obviously as the session library was loaded in the controller, seems that I can't change the config...

How can I handle this?
have the session expire on close if the user don't want to be remembered and keep it if the user want to be remembered...

Thanks...
