title: Removing index.php on CodeIgniter 2.2.0
body: <p>I am running Apache 2.2.22 on Ubuntu 12.04.3 (Oracle VM on Windows 8.1).
  Using the PHP phpinfo() function I see mod_rewrite in the apache2handler section under Loaded Modules, so mod_rewrite is enabled.</p>
  
  <p>I made the following changes to my CI config file (application/config/config.php),</p>
  
  <pre><code>$config['index_page'] = 'index.php'; to: $config['index_page'] = '';
  $config['uri_protocol'] = 'AUTO'; to: $config['uri_protocol']   = 'PATH_INFO';
  </code></pre>
  
  <p>I have tried numerous versions this(.htaccess file located in the root directory of CI ):</p>
  
  <pre><code>RewriteEngine on
  RewriteCond $1 !^(index\.php|images|robots\.txt)
  RewriteRule ^(.*)$ /index.php/$1 [L]
  </code></pre>
  
  <p>but have yet to get it to work.
  What else am I missing here?</p>
