-==========================================
-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.
-
-See the :ref:`Apache/mod_python documentation<howto-deployment-modpython>` for 
-directions on serving static media, and the `mod_wsgi documentation`_ for an 
-explanation of other directives and configuration options you can use.
-
-Details
-=======
-
-For more details, see the `mod_wsgi documentation`_, which explains the above in
-more detail, and walks through all the various options you've got when deploying
-under mod_wsgi.

+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

-Note, however, that the ``self.my_view`` function registered above will *not*
-have any permission check done; it'll be accessible to the general public. Since
-this is usually not what you want, Django provides a convience wrapper to check

-``self.admin_site.admin_view`` inside a ``ModelAdmin`` instance); use it like

+However, the ``self.my_view`` function registered above suffers from two
+problems:

+  * It will *not* provide any header details to prevent caching. This means if

+to check permissions and mark the view as non-cacheable. This wrapper is
+:meth:`AdminSite.admin_view` (i.e.  ``self.admin_site.admin_view`` inside a
+``ModelAdmin`` instance); use it like so::
 
     class MyModelAdmin(admin.ModelAdmin):
         def get_urls(self):
 
     (r'^my_view/$', self.admin_site.admin_view(self.my_view))
 
-This wrapping will protect ``self.my_view`` from unauthorized access.
+This wrapping will protect ``self.my_view`` from unauthorized access and will
+apply the ``django.views.decorators.cache.never_cache`` decorator to make sure
+it is not cached if the cache middleware is active.
+
+If the page is cacheable, but you still want the permission check to be performed,
+you can pass a ``cacheable=True`` argument to :meth:`AdminSite.admin_view`::
+
+    (r'^my_view/$', self.admin_site.admin_view(self.my_view, cacheable=True))

 ``AdminSite`` objects
 =====================
 
-.. class:: AdminSite
+.. class:: AdminSite(name=None)
 
 A Django administrative site is represented by an instance of
 ``django.contrib.admin.sites.AdminSite``; by default, an instance of
 Python class), and register your models and ``ModelAdmin`` subclasses
 with it instead of using the default.
 
+.. versionadded:: 1.1
+
+When constructing an instance of an ``AdminSite``, you are able to provide
+a unique instance name using the ``name`` argument to the constructor. This
+instance name is used to identify the instance, especially when
+:ref:`reversing admin URLs <admin-reverse-urls>`. If no instance name is
+provided, a default instance name of ``admin`` will be used.
+
 ``AdminSite`` attributes
 ------------------------
 
 
 .. note::
     Any view you render that uses the admin templates, or extends the base
-    admin template, should include in it's context a variable named
-    ``admin_site`` that contains the name of the :class:`AdminSite` instance. For
-    :class:`AdminSite` instances, this means ``self.name``; for :class:`ModelAdmin`
-    instances, this means ``self.admin_site.name``.
+    admin template, should provide the ``current_app`` argument to
+    ``RequestContext`` or ``Context`` when rendering the template.  It should
+    be set to either ``self.name`` if your view is on an ``AdminSite`` or
+    ``self.admin_site.name`` if your view is on a ``ModelAdmin``.
 
 .. _admin-reverse-urls:
 
 
 The :class:`AdminSite` provides the following named URL patterns:

+If you want to find a URL in a specific admin instance, provide the name of that instance

 URL dispatcher
 ==============
 
+.. module:: django.core.urlresolvers
+
 A clean, elegant URL scheme is an important detail in a high-quality Web
 application. Django lets you design URLs however you want, with no framework
 limitations.
 patterns
 --------
 
+.. function:: patterns(prefix, pattern_description, ...)
+
 A function that takes a prefix, and an arbitrary number of URL patterns, and
 returns a list of URL patterns in the format Django needs.
 
 The first argument to ``patterns()`` is a string ``prefix``. See
-"The view prefix" below.
+`The view prefix`_ below.
 
 The remaining arguments should be tuples in this format::
 
 
 .. versionadded:: 1.0
 
+.. function:: url(regex, view, kwargs=None, name=None, prefix='')
+
 You can use the ``url()`` function, instead of a tuple, as an argument to
 ``patterns()``. This is convenient if you want to specify a name without the
 optional extra arguments dictionary. For example::
 handler404
 ----------
 
+.. data:: handler404
+
 A string representing the full Python import path to the view that should be
 called if none of the URL patterns match.
 
 handler500
 ----------
 
+.. data:: handler500
+
 A string representing the full Python import path to the view that should be
 called in case of server errors. Server errors happen when you have runtime
 errors in view code.
 include
 -------
 
+.. function:: include(<module or pattern_list>)
+
 A function that takes a full Python import path to another URLconf module that
 should be "included" in this place.
 
 .. versionadded:: 1.1
 
-:meth:``include`` also accepts as an argument an iterable that returns URL
+:func:`include` also accepts as an argument an iterable that returns URL
 patterns.
 
 See `Including other URLconfs`_ below.
 
 .. versionadded:: 1.1
 
-Another posibility is to include additional URL patterns not by specifying the
+Another possibility is to include additional URL patterns not by specifying the
 URLconf Python module defining them as the `include`_ argument but by using
 directly the pattern list as returned by `patterns`_ instead. For example::
 
         (r'^credit/', include(extra_patterns)),
     )
 
+This approach can be seen in use when you deploy an instance of the Django
+Admin application. The Django Admin is deployed as instances of a
+:class:`AdminSite`; each :class:`AdminSite` instance has an attribute
+``urls`` that returns the url patterns available to that instance. It is this
+attribute that you ``include()`` into your projects ``urlpatterns`` when you
+deploy the admin instance.
+

 Captured parameters
 In the above example, the captured ``"username"`` variable is passed to the
 included URLconf, as expected.
 
+.. _topics-http-defining-url-namespaces:
+
+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>`.
+
 Passing extra options to view functions
 =======================================
 
     name, will decrease the chances of collision. We recommend something like
     ``myapp-comment`` instead of ``comment``.
 
+.. _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 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

+
+    * ``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``.

 Utility methods
 ===============
 
 your code, Django provides the following method (in the
 ``django.core.urlresolvers`` module):
 
-.. currentmodule:: django.core.urlresolvers
-.. function:: reverse(viewname, urlconf=None, args=None, kwargs=None)
+.. function:: reverse(viewname, urlconf=None, args=None, kwargs=None, current_app=None)
 
 ``viewname`` is either the function name (either a function reference, or the
 string version of the name, if you used that form in ``urlpatterns``) or the
 matching against incoming URLs and sending them off to views, but you cannot
 reverse such patterns.
 
+.. versionadded:: 1.1
+
+The ``current_app`` argument allows you to provide a hint to the resolver
+indicating the application to which the currently executing view belongs.
+This ``current_app`` argument is used as a hint to resolve application
+namespaces into URLs on specific application instances, according to the
+:ref:`namespaced URL resolution strategy <topics-http-reversing-url-namespaces>`.

 .. admonition:: Make sure your views are all correct
 
     As part of working out which URL names map to which patterns, the
 The :func:`django.core.urlresolvers.resolve` function can be used for resolving
 URL paths to the corresponding view functions. It has the following signature:
 
-.. currentmodule:: django.core.urlresolvers
 .. function:: resolve(path, urlconf=None)
 
 ``path`` is the URL path you want to resolve. As with ``reverse()`` above, you
