Dovrei specificare l'ambiente Rails come RackEnv staging per le versioni Rails>=3.x
Questa configurazione ha risolto il problema.
[email protected]:/etc/apache2/sites-enabled$ cat app_staging
<VirtualHost *:80>
ServerName myappstaging.org
ServerAlias *.myappstaging.org
DocumentRoot /home/anand/public_html/app_staging/current/public
RackEnv staging
RewriteEngine on
RewriteCond %{REQUEST_METHOD} ^OPTIONS
RewriteRule .* - [R=405,L]
XSendFile on
</VirtualHost>
