Virtual Host Filter
From http://groups.google.com/group/cherrypy-users/browse_thread/thread/f393540fe278e54d:
For various reasons I need several domains to point to different parts of a
single website structure as well as to their own "homepage" EG
http://www.mydom1.com -> root
http://www.mydom2.com -> root/mydom2/
http://www.mydom3.com -> root/mydom3/
http://www.mydom4.com -> under construction page
but also to have http://www.mydom1.com/mydom2/ etc to be valid pages in
their own right.

import cherrypy
from basefilter import BaseFilter
class VirtualHostFilter(BaseFilter):
"""Filter that changes the ObjectPath based on the Host.
Useful when running multiple sites within one CP server.
