Using Apache2 to route http from domain/subdomain to port 3000 server

To easy test Rails Application-Server (mongrel, webrick, thin) in development through a full domain/subdomain, you can use the Apache-Proxy-Ability. So, every traffic will be redirected transparently to that running application server.

a2enmod proxy
a2enmod proxy_balancer
a2enmod proxy_http

Plesk-specific apache vhost.conf/vhost_ssl.conf

DocumentRoot /home/stefan/repos/empfehlungsbund/public
<Proxy balancer://thinservers>
  BalancerMember http://127.0.0.1:3000
</Proxy>

ProxyPreserveHost On
#ProxyPass /assets !
ProxyPass / balancer://thinservers/
ProxyPassReverse / balancer://thinservers/

<Proxy *>
Order deny,allow
Allow from all
</Proxy>

(vhost_ssl.conf is identical)

Reload Plesk-Config and restart apache2:

/usr/local/psa/admin/bin/websrvmng -a
/etc/init.d/apache2 restart

Now, we only have to start our dev-Server on port 3000, and done! This is useful for developing/testing facebook, that requires a SSL-domain.
