Redirection error

On a client server has a project in CakePHP, I created a folder called halldafama in the root of the server. I need to access this folder, but when trying to access it returns me: Error: The requested address '//halldafama/' was not found on this server. being this folder halldafama has nothing to do with CakePHP.

My HTACCESS

<IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteRule    ^$ app/webroot/    [L]
   RewriteRule    (.*) app/webroot/$1 [L]
</IfModule>
