Hi Nginx.

Properly so simple you may laugh , but this world save my day :-)

RewriteEngine On

RewriteBase /

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*)$ site/$1 [NC,L,QSA]
RewriteRule ^$ site/index.php [NC,L,QSA]

When you hit the domain.com i simple need to access domain.com/site/index.php.

After this info , i would like to study the rules more intense.
But i'm in a shortage of time right now.

Thanks In advance..
