I have deployed Zend Framework application on server. When I browse with www.mydomial.com/myproject/public it is call indexController/indexMethod. Page is showing ok. I have another controller AuthController and a method loginAction in this controller. When I call www.mydomain.com/myproject/public/auth/login it showing Internal Server Error 500.

myproject .htaccess file content is -

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

my project is deployed in 1and1.com server
