Push Play application in production

I'm working on Fancy project closed to be released. I'm using Debian Squeeze 6 but I seems that the Play documentation is not enough clear about this subject.

Active modules needed, not only proxy as the play documentation said.

a2enmod proxy
a2enmod proxy_http
/etc/init.d/apache2 restart

cat /etc/apache2/mods-available/proxy.conf

<IfModule mod_proxy.c>

# If you want to use apache2 as a forward proxy, uncomment the
# 'ProxyRequests On' line and the <Proxy *> block below.
# WARNING: Be careful to restrict access inside the <Proxy *> block.
# Open proxy servers are dangerous both to your network and to the
# Internet at large.
#
# If you only want to use apache2 as a reverse proxy/gateway in
# front of some web application server, you DON'T need
# 'ProxyRequests On'.

ProxyRequests Off

<Proxy *>
        AddDefaultCharset off
        Order deny,allow
#        Deny from all
        Allow from app.kassandre.org
</Proxy>

# Enable/disable the handling of HTTP/1.1 "Via:" headers.
# ("Full" adds the server version; "Block" removes all outgoing Via: headers)
# Set to one of: Off | On | Full | Block
ProxyVia Full

</IfModule>

cat /etc/apache2/sites-available/app-kassandre 

# Connect play to Apache2
<virtualhost *:80>
    ServerName mysite.org
    ServerAlias mysite.org

    ServerAdmin victor@unhook.eu

    ErrorLog /home/mysite/logs/mysite.error.log
    CustomLog /home/mysite/logs/mysite.access.log common

    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:9000/
    ProxyPassReverse / http://127.0.0.1:9000/

</virtualhost>

/etc/init.d/apache2 restart
# or, more safe
/etc/init.d/apache2 reload
