Session problem! PLS help!

I can't test your second method because i want the message to be shown only one time.

In test function i do:
=============================================================================================
$this->session->set_userdata('test', 'Hello world!');
redirect('/welcome');

And in index function:
=============================================================================================
echo $this->session->userdata('test');

But then i can't remove de Hello world!.

If i do $this->session->sess_destroy(); i get the header error, the same for unset_userdata.

Thank you again for your reply.
