Make CodeIgniter work behind apache with nginx as intermediary

Finally solved by setting uri_protocol = PATH_INFO

application/config/config.php

PHP Code:

$config['base_url'] = $_SERVER['HTTP_HOST'] == '10.20.30.40' ? 'http://10.20.30.40/ci/' : 'http://www.subdomain.company.xxx/ci/'; 
$config['index_page'] = '';
$config['uri_protocol'] = 'PATH_INFO'; 


and .htaccess like

Code:

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

Now it is working perfect locally and loaded from Internet
