I've search online and been reading documentation for Apache, Passenger, Rack, etc, but have yet to find a solution to my problem.
I have several Rack (ruby)-based apps, located in
/home/web/sites/app1
/home/web/sites/app2
/home/web/sites/app3
app1 is a Sintra app, app2 is Padrino and app3 is Rails.
I would like to run these apps under different ports (assuming server IP is 50.60.70.101):
50.60.70.101:4567 -> app1
50.60.70.101:3000 -> app2
50.60.70.101:80   -> app3
What is the correct way to configure Apache's virtual host file to achieve this?
I have 3 files in /etc/apache2/sites-available/ with this type of configuration (with changed IPs):
<VirtualHost *:4567>
    RackEnv         production
    DocumentRoot    /home/web/sites/app1/public
    <Directory      /home/web/sites/app1/public>
        Order   allow,deny
        Allow   from all
        Options -MultiViews
        #AllowOverride All
    </Directory>
</VirtualHost>
But I cannot access app1 at 50.60.70.101:4567 (app3 does work on port 80, though).
