ForwardDirectory (and then MirrorDirectory) is tuned to act as a root 
resource.
For example, if you set mirrors to http://www.foo.com/
in a directory /toto/ of your server http://www.bar.com/
then all request to http://www.bar.com/toto/something
will be redirected to http://www.foo.com/toto/something

So the name you want to use for a directory must be exactly the one of 
the mirrored server. If you want to mirror the whole server, you need to 
install the MirrorDirectory as your root resource, set the local-root to 
root, then you can access your "normal" space with the root/ prefix
(It is like the Proxy, both extends ForwardDirectory).
To change the behaviour of MirrorDirectory (ie: if you want to mirror 
UNDER one directory, which is unsafe, link-wise, because of the 
possibility of absolute links in pages served), simply subclass 
MirrorDirectory.
