Sometimes you have a Web application in several variants. A prominent
example is the same application for different languages. In such a
case, you will want to separate the common parts out and maintain them
just once. Nevertheless, the variant parts should be able to reference
the common parts as if they had not been factored out.

This situation is the main use case for Mirrowing Folder. A mirrowing
folder is a folder that is able to map one subfolder into each of its
other subfolders. Under the assumption that all subfolders have
essentially the same structure, the subfolders of the mirrowed folder
are recursively mapped during traversal onto the corresponding
subfolders in the folder selected by the request URL. Content there
can access the mirrowed objects (almost) as if they were physically
located beside them.

Mirrowing Folder is similar to Transparent Folder but what becomes
visible depends on the request URL. Therefore, name clashes are less
of a problem.
