I'm trying to setup Chiliproject (a ruby application for project management) I have setup my Apache already. However I want the Chiliproject to be like http://abc.com/Chiliproject as I want the abc.com to be used for other application. Following is my Chiliproject vhost setting: ServerName abc.com DocumentRoot /var/www/chiliproject/public Alias /chiliproject /var/www/chiliproject/public Options -MultiViews AllowOverride all When I go to abc.com, the Chiliproject page will appear but when I go to abc.com/chiliproject, I will reach the 404 page not found instead. If I change the DocumentRoot to /var/www, the page abc.com will be what I want, but the abc.com/chiliproject will comes to the 'Directory view' of my page.
