the problem is that we are getting a 404 for 
http://bochenek.ch/vantaa/javax.faces.resource/jsf.js.faces?ln=javax.faces

so as a quick hack, we simply re-write it using a regular html script
tag (without /vantaa/ because apache2 redirects there already)
<script type="text/javascript"
src="/vantaa/javax.faces.resource/jsf.js.faces?ln=javax.faces"></script></head><body>
