The second URL to /foo/bran/2.html is a completely separate HTTP request
based on your description.  Therefore the regions will run as for the
prior request.  However, now the pattern matches /foo/bran/* so the
environment variable "CONFIG_DIR" is set to "/configs/foobran".  
Assuming that the browser sent the same auth header, CGIPassword will
decode this into REMOTE_USER and REMOTE_PASSWD, your Authorizer will
be able to grant access, and the request will run.

Does this clear things up?
