Middleware to make internal requests and forward requests internally.
When applied, several keys are added to the environment that will allow
you to trigger recursive redirects and forwards.
paste.recursive.include:
When you call
``environ['paste.recursive.include'](new_path_info)`` a response
will be returned. The response has a ``body`` attribute, a
``status`` attribute, and a ``headers`` attribute.
paste.recursive.script_name:
The ``SCRIPT_NAME`` at the point that recursive lives. Only
paths underneath this path can be redirected to.
paste.recursive.old_path_info:
A list of previous ``PATH_INFO`` values from previous redirects.
Raise ``ForwardRequestException(new_path_info)`` to do a forward
(aborting the current request).

A WSGI middleware that allows for recursive and forwarded calls.
All these calls go to the same 'application', but presumably that
application acts differently with different URLs. The forwarded
URLs must be relative to this container.
Interface is entirely through the ``paste.recursive.forward`` and
``paste.recursive.include`` environmental keys.

The forwarder will try to restart the request, except with
the new `path` (replacing ``PATH_INFO`` in the request).
It must not be called after and headers have been returned.
It returns an iterator that must be returned back up the call
stack, so it must be used like:
.. code-block:: python
return environ['paste.recursive.forward'](path)
Meaningful transformations cannot be done, since headers are
sent directly to the server and cannot be inspected or
rewritten.

Starts another request with the given path and adding or
overwriting any values in the `extra_environ` dictionary.
Returns an IncludeResponse object.

Like Includer, but just stores the app_iter response
(be sure to call close on the response!)
