Always redirect me to the home page

Hi,

I ' ll show you myvonfiguration

application  > .htaccess 

<IfModule authz_core_module>
    Require all denied
</IfModule>
<IfModule !authz_core_module>
    Deny from all
</IfModule>

I've tried to change this htaccess in many times but it's not working

for example : 

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

------------------------------------------------------------------------------------------------------------------------------------------
for the configuration 

- base_url = "http://xxxxxxxx.com/Projet"

- index_page = 'index.php'

in the route.php

$route['default_controller'] = 'HomeController';

it will redirect me automatickly in the function index of the controller, when i change the view in this index,the code work successfully but when i try to enter in other controller with a link or in a url,it' s not working,it redirect me forever in the homepage that i define in the function index

I think that it is a problem of htaccess but i don't know how 

Thanks a lot for every help
