问题 I'm just developing a little WebApp with PHP and for routing, I use AltoRouter. So far, I was only developing and testing offline, so on my localhost. Now, to see the behaviour on a server, I uploaded my code, fixed the database connection to fit for the MySQL-Server running on the server (which is Ubuntu 14.04) and tried to get it started. First, what I'm doing for the routing, is a simple .htaccess , looking like that: RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f
