Remove index.php from URL

Following the instructions at http://www.codeigniter.com/userguide3/general/urls.html, I can get the index.php removed from the URL of regular links, e.g., http://www.foo.com/index.php, using this .htaccess entry:

Code:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

Now, there is a scenario where there is a redirect inside of a controller that should go to something like http://www.foo.com/bar/foo However, the redirect goes to http://www.foo.com/index.php/bar/foo instead. Directly typing http://www.foo.com/bar/foo works fine. It's just the redirect that adds the index.php for some reason.

The redirect is very simple:

PHP Code:

   public function index() 
    { 
    redirect('/foo/bar', 'data');
    } 


How do I can get rid of the index.php in the URL of a redirect? Thanks in advance!
