multiple applications routing problem

[eluser]Unknown[/eluser]
I have created two applications the frontend and the backend, the front end works perfectly but the backend doesn't...

I copied the frontend folder and pasted it as backend, then I copied the index.php and pasted it in another folder 'admin/index.php', I changed the $system_folder = "../framework"; and $application_folder = "../applications/backend"; so it works with http://localhost/admin/...


the problem starts here, when I try to create another controller apart from the default one...

I created this controller in backend/controllers/forum.php:

class Forum extends Controller {
function Forum()
{
parent::Controller();
}
function home()
{
$this->smarty->view('forum/home');
}
}

and I write in the backend/config/routes.php:

$route['admin/forum'] = "forum/home";

so I expect this to work:

http://localhost/admin/forum

but it doesn't ... am I missing something? any ideas?

it works if I write the full link

http://localhost/admin/index.php/forum/home/index.php

This is my .htaccess:

# Turn on URL rewriting
RewriteEngine On

# Installation directory
RewriteBase /

# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# Rewrite all other URLs to index.php/URL
RewriteCond $1 !^(index\.php|robots\.txt|skins)
RewriteRule ^(.*)$ /index.php/$1 [L]

Thanks!
