Simple! Just need to change a setting in the .htaccess file. I am using Laravel 4, you might be using some other version but the method should apply nevertheless. I use an alias to point to this directory.
Add this line “RewriteBase /l4″ to your .htaccess where l4 is your sub directory or folder.
<IfModule mod_rewrite.c> Options -MultiViews RewriteEngine On RewriteBase /l4 RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] </IfModule>
Have fun!
