 #  This sample of `parameter_dict` will make apache listening to :
 #  From to `backend-list`:
 #   - 0.0.0.0:8000 redirecting internaly to http://10.0.0.10:8001 and
 #   - [::1]:8000 redirecting internaly to http://10.0.0.10:8001
72
 #  only accepting requests from clients who provide a valid SSL certificate trusted in `ca-cert-dir`.
73 74 75 76 77 78 79 80 81 82 83 84
 #   - 0.0.0.0:8002 redirecting internaly to http://10.0.0.10:8003
 #   - [::1]:8002 redirecting internaly to http://10.0.0.10:8003
 #  accepting requests from any client.
 #
 # From zope-virtualhost-monster-backend-dict`:
 #   - [::1]:8004 with some path based rewrite-rules redirecting to:
 #     * http://10.0.0.10/8001 when path matches /zope-1(.*)
 #     * http://10.0.0.10/8002 when path matches /zope-2(.*)
 #   with some VirtualHostMonster rewrite rules so zope writes URLs with
 #  [::1]:8004 as server name.
 #  For more details, refer to
 #  https://docs.zope.org/zope2/zope2book/VirtualHosting.html#using-virtualhostroot-and-virtualhostbase-together
