explanation of other directives and configuration options you can use.
Serving media files
===================
Django doesn't serve media files itself; it leaves that job to whichever Web
server you choose.
We recommend using a separate Web server -- i.e., one that's not also running
Django -- for serving media. Here are some good choices:
* lighttpd_
* Nginx_
* TUX_
* A stripped-down version of Apache_
* Cherokee_
If, however, you have no option but to serve media files on the same Apache
``VirtualHost`` as Django, you can set up Apache to serve some URLs as
static media, and others using the mod_wsgi interface to Django.
This example sets up Django at the site root, but explicitly serves ``robots.txt``,
``favicon.ico``, any CSS file, and anything in the ``/media/`` URL space as a static
file. All other URLs will be served using mod_wsgi::
Alias /robots.txt /usr/local/wsgi/static/robots.txt
Alias /favicon.ico /usr/local/wsgi/static/favicon.ico
AliasMatch /([^/]*\.css) /usr/local/wsgi/static/styles/$1

directly the pattern list as returned by `patterns`_ instead. For example::

Admin application. The Django Admin is deployed as instances of a

``urls`` that returns the url patterns available to that instance. It is this

Defining URL Namespaces
-----------------------
When you need to deploy multiple instances of a single application, it can be
helpful to be able to differentiate between instances. This is especially
important when using _`named URL patterns <naming-url-patterns>`, since
multiple instances of a single application will share named URLs. Namespaces
provide a way to tell these named URLs apart.
A URL namespace comes in two parts, both of which are strings:
* An **application namespace**. This describes the name of the application
that is being deployed. Every instance of a single application will have
the same application namespace. For example, Django's admin application
has the somewhat predictable application namespace of ``admin``.
* An **instance namespace**. This identifies a specific instance of an
application. Instance namespaces should be unique across your entire
project. However, an instance namespace can be the same as the
application namespace. This is used to specify a default instance of an
application. For example, the default Django Admin instance has an
instance namespace of ``admin``.
URL Namespaces can be specified in two ways.
Firstly, you can provide the application and instance namespace as arguments
to ``include()`` when you construct your URL patterns. For example,::
(r'^help/', include('apps.help.urls', namespace='foo', app_name='bar')),
This will include the URLs defined in ``apps.help.urls`` into the application
namespace ``bar``, with the instance namespace ``foo``.
Secondly, you can include an object that contains embedded namespace data. If
you ``include()`` a ``patterns`` object, that object will be added to the
global namespace. However, you can also ``include()`` an object that contains
a 3-tuple containing::
(<patterns object>, <application namespace>, <instance namespace>)
This will include the nominated URL patterns into the given application and
instance namespace. For example, the ``urls`` attribute of Django's
:class:`AdminSite` object returns a 3-tuple that contains all the patterns in
an admin site, plus the name of the admin instance, and the application
namespace ``admin``.
Once you have defined namespaced URLs, you can reverse them. For details on
reversing namespaced urls, see the documentation on :ref:`reversing namespaced
URLs <topics-http-reversing-url-namespaces>`.

URL namespaces
--------------
.. versionadded:: 1.1
Namespaced URLs are specified using the ``:`` operator. For example, the main
index page of the admin application is referenced using ``admin:index``. This
indicates a namespace of ``admin``, and a named URL of ``index``.
Namespaces can also be nested. The named URL ``foo:bar:whiz`` would look for
a pattern named ``whiz`` in the namespace ``bar`` that is itself defined within
the top-level namespace ``foo``.
When given a namespaced URL (e.g. ``myapp:index``) to resolve, Django splits
the fully qualified name into parts, and then tries the following lookup:
1. First, Django looks for a matching application namespace (in this
example, ``myapp``). This will yield a list of instances of that
application.
2. If there is a ``current`` application defined, Django finds and returns
the URL resolver for that instance. The ``current`` can be specified
as an attribute on the template context - applications that expect to
have multiple deployments should set the ``current_app`` attribute on
any ``Context`` or ``RequestContext`` that is used to render a
template.
The current application can also be specified manually as an argument
to the :func:`reverse()` function.
3. If there is no current application. Django looks for a default
application instance. The default application instance is the instance
that has an instance namespace matching the application namespace (in
this example, an instance of the ``myapp`` called ``myapp``).
4. If there is no default application instance, Django will pick the first
deployed instance of the application, whatever its instance name may be.
5. If the provided namespace doesn't match an application namespace in
step 2, Django will attempt a direct lookup of the namespace as an
instance namespace.
If there are nested namespaces, these steps are repeated for each part of the
namespace until only the view name is unresolved. The view name will then be
resolved into a URL in the namespace that has been found.
To show this resolution strategy in action, consider an example of two instances
of ``myapp``: one called ``foo``, and one called ``bar``. ``myapp`` has a main
index page with a URL named `index`. Using this setup, the following lookups are
possible:
* If one of the instances is current - say, if we were rendering a utility page
in the instance ``bar`` - ``myapp:index`` will resolve to the index page of
the instance ``bar``.
* If there is no current instance - say, if we were rendering a page
somewhere else on the site - ``myapp:index`` will resolve to the first
registered instance of ``myapp``. Since there is no default instance,
the first instance of ``myapp`` that is registered will be used. This could
be ``foo`` or ``bar``, depending on the order they are introduced into the
urlpatterns of the project.
* ``foo:index`` will always resolve to the index page of the instance ``foo``.
If there was also a default instance - i.e., an instance named `myapp` - the
following would happen:
* If one of the instances is current - say, if we were rendering a utility page
in the instance ``bar`` - ``myapp:index`` will resolve to the index page of
the instance ``bar``.
* If there is no current instance - say, if we were rendering a page somewhere
else on the site - ``myapp:index`` will resolve to the index page of the
default instance.
* ``foo:index`` will again resolve to the index page of the instance ``foo``.
