-==========================================
-How to use Django with Apache and mod_wsgi
-==========================================
-
-Deploying Django with Apache_ and `mod_wsgi`_ is the recommended way to get
-Django into production.
-
-.. _Apache: http://httpd.apache.org/
-.. _mod_wsgi: http://code.google.com/p/modwsgi/
-
-mod_wsgi is an Apache module which can be used to host any Python application
-which supports the `Python WSGI interface`_, including Django. Django will work
-with any version of Apache which supports mod_wsgi.
-
-.. _python wsgi interface: http://www.python.org/dev/peps/pep-0333/
-
-The `official mod_wsgi documentation`_ is fantastic; it's your source for all
-the details about how to use mod_wsgi. You'll probably want to start with the
-`installation and configuration documentation`_.
-
-.. _official mod_wsgi documentation: http://code.google.com/p/modwsgi/
-.. _installation and configuration documentation: http://code.google.com/p/modwsgi/wiki/InstallationInstructions
-
-Basic Configuration
-===================
-
-Once you've got mod_wsgi installed and activated, edit your ``httpd.conf`` file
-and add::
-
-    WSGIScriptAlias / /path/to/mysite/apache/django.wsgi
-
-The first bit above is the url you want to be serving your application at (``/``
-indicates the root url), and the second is the location of a "WSGI file" -- see
-below -- on your system, usually inside of your project. This tells Apache
-to serve any request below the given URL using the WSGI application defined by that file.
-
-Next we'll need to actually create this WSGI application, so create the file
-mentioned in the second part of ``WSGIScriptAlias`` and add::
-
-    import os
-    import sys
-
-    os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
-
-    import django.core.handlers.wsgi
-    application = django.core.handlers.wsgi.WSGIHandler()
-
-If your project is not on your ``PYTHONPATH`` by default you can add::
-
-    sys.path.append('/usr/local/django')
-
-just above the final ``import`` line to place your project on the path. Remember to
-replace 'mysite.settings' with your correct settings file, and '/usr/local/django'
-with your own project's location.
-

+==========================================
+How to use Django with Apache and mod_wsgi
+==========================================
+
+Deploying Django with Apache_ and `mod_wsgi`_ is the recommended way to get
+Django into production.
+
+.. _Apache: http://httpd.apache.org/
+.. _mod_wsgi: http://code.google.com/p/modwsgi/
+
+mod_wsgi is an Apache module which can be used to host any Python application
+which supports the `Python WSGI interface`_, including Django. Django will work
+with any version of Apache which supports mod_wsgi.
+
+.. _python wsgi interface: http://www.python.org/dev/peps/pep-0333/
+
+The `official mod_wsgi documentation`_ is fantastic; it's your source for all
+the details about how to use mod_wsgi. You'll probably want to start with the
+`installation and configuration documentation`_.
+
+.. _official mod_wsgi documentation: http://code.google.com/p/modwsgi/
+.. _installation and configuration documentation: http://code.google.com/p/modwsgi/wiki/InstallationInstructions
+
+Basic Configuration
+===================
+
+Once you've got mod_wsgi installed and activated, edit your ``httpd.conf`` file
+and add::
+
+    WSGIScriptAlias / /path/to/mysite/apache/django.wsgi
+
+The first bit above is the url you want to be serving your application at (``/``
+indicates the root url), and the second is the location of a "WSGI file" -- see
+below -- on your system, usually inside of your project. This tells Apache
+to serve any request below the given URL using the WSGI application defined by that file.
+
+Next we'll need to actually create this WSGI application, so create the file
+mentioned in the second part of ``WSGIScriptAlias`` and add::
+
+    import os
+    import sys
+
+    os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
+
+    import django.core.handlers.wsgi
+    application = django.core.handlers.wsgi.WSGIHandler()
+
+If your project is not on your ``PYTHONPATH`` by default you can add::
+
+    sys.path.append('/usr/local/django')
+
+just above the final ``import`` line to place your project on the path. Remember to
+replace 'mysite.settings' with your correct settings file, and '/usr/local/django'
+with your own project's location.
+
+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
+
+    Alias /media/ /usr/local/wsgi/static/media/
+
+    <Directory /usr/local/wsgi/static>
+    Order deny,allow
+    Allow from all
+    </Directory>
+
+    WSGIScriptAlias / /usr/local/wsgi/scripts/django.wsgi
+
+    <Directory /usr/local/wsgi/scripts>
+    Order allow,deny
+    Allow from all
+    </Directory>
+
+.. _lighttpd: http://www.lighttpd.net/
+.. _Nginx: http://wiki.codemongers.com/Main
+.. _TUX: http://en.wikipedia.org/wiki/TUX_web_server
+.. _Apache: http://httpd.apache.org/
+.. _Cherokee: http://www.cherokee-project.com/

+More details on configuring a mod_wsgi site to serve static files can be found
+in the mod_wsgi documentation on `hosting static files`_.

+options you've got when deploying under mod_wsgi.

+
+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>`.

+.. _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``.
