ejabberd - BOSH module not started
===

I'm trying to create a custom Facebook chat, I'm using:

 1. ejabberd
 2. strophe
 3. apache

The apache is on one pc and the ejabberd is on a different machine, I proxy my request using 

    <Proxy *>
          Order deny,allow
          Deny from all
          Allow from 127.0.0.1
    </Proxy>
    ProxyPass /http-bind http://my_bosh_domain:5280/http-bind/ nocanon
    ProxyPassReverse /http-bind http://my_bosh_domain:5280/http-bind/

I log my requests and get the following error:

    <body xmlns='http://jabber.org/protocol/httpbind' type='terminate' condition='internal-server-error'>BOSH module not started</body> 

when I check `http://my_bosh_domain:5280/http-bind/` from my browser I can see:

    ejabberd mod_http_bind
    
    An implementation of XMPP over BOSH (XEP-0206)
    
    This web page is only informative. To use HTTP-Bind you need a Jabber/XMPP client that supports it.

What am I missing?
