Changing db in the middle of a script

[eluser]Skinnpenal[/eluser]
Hi guys

I have CI autoloading the database library, so when the app starts it connects to database specified in my config/database.php

Now, in the middle of this app, I need to connect to a different database .. replacing the current connection.

How do I do this "the right way"?

I tried doing

Code:

$this->load->database($config);

and supplying a new config, but that does absolutely nothing, as far as I can tell.

EDIT:

I got this to work:

Code:

$this->db->close();
$this->db->initialize($config);

Is that the proper way to do it?

And another question:
I use database based sessions (because of freak_auth), which means that when I connect to this new database, freak_auth no longer has access to the session it created in the beginning of the script. Any ideas how to fix that?
