Session creates new session id on every page load

That define() is a bit outdated (although it should work) and CI has a native command for it now:

Code:

$this->input->is_ajax_request()

Not sure about your last question as you aren't really sending "ajax", you are sending post variables via an ajax request. How are you retrieving the post variables? By the way you are sending them it looks like it would be

Code:

$one = $this->input->post('one');
$two = $this->input->post('two');

etc.

Are you checking in that controller that receives those to see if they are being sent and received correctly?
