Use function instead of a controller

One thing with routes...you need to have the order go from the uri with the most segments, to least.

Code:

$route['main/(:any)'] = "main/redirect"; //two segments, main + (:any)
$route['main'] = "main/redirect"; //one segment, main

In routes, you can also pass in any captured segments to the controller/method.

Code:

$route['main/(:any)'] = "main/redirect/$1"; //$1 will be (:any)

Then in main{}...

Code:

function redirect($url = null) //$url is (:any) from the route
{
  if ( ! is_null($url))
  {
    redirect($url);
  }
}

You also shouldn't have to have http:// AND base_url(). base_url() contains the http://, or at least it should in the config. Also, when using redirect(), CI adds the base_url() automatically so all you need to do is pass it the segments

Code:

redirect($this->uri->segment(2));  //redirects to base_url() + segments
