CodeIgniter redirect loop in subfolder on server - codeigniter

Question

I'm stuck with redirect loop when I deploy the files from localhost to my server.
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
The site is multilingual and I'm using .htaccess file to remove the index.php from the uri. I'm trying to deploy the site to a subfolder in my domain (i.e http://www.mydomain.com/subfolder) and ideally I want the urls like this (http://www.mydomain.com/subfolder/en/welcome)
My .htaccess file:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]
I have also tried:
RewriteEngine on
RewriteBase /subfolder/
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]
My config.php:
$config['base_url'] = 'http://www.mydomain.com/subfolder/';
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';
My routes.php:
$route['default_controller'] = "home";
$route['404_override'] = '';
$route['^../products/(:num)'] = "products/products_list/index/$1";
$route['^../products'] = "products/products_list/index";
$route['^../products/detail/(:num)'] = "products/product/index/$1";
$route['^../(.+)$'] = "$2";
And finally MY_Config class for i18n:
class MY_Config extends CI_Config {
function site_url($uri = '')
{
if (is_array($uri))
{
$uri = implode('/', $uri);
}
if (function_exists('get_instance'))
{
$CI =& get_instance();
$uri = $CI->lang->localized($uri);
}
return parent::site_url($uri);
}
}
This setup works fine in my local environment, I access via http://local.subfolder.com, I set a virtual host to do this, but this setup doesn't work when I deploy to the server in a subfolder.
I would be really glad if someone can point where the problem is. Sorry for the long post, but wanted to give as much as information.
Thanks in advance

Answer 1

I'd try removing the trailing slash from RewriteBase
RewriteBase /subfolder
And also modifying your RewriteCond
RewriteEngine On
RewriteBase /subfolder
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
I've noticed that using the ? before /$1 seems to work sometimes in CI too.
Very useful doc:

Answer 2

if u want to use the htaccess for a particular folder., u just put your htaccess with in that folder. for ex.,
if ur using five virtual hosting like v1,v2,v3,v4,v5. And if u want to use your htaccess in v3, just put that file within that folder.
