Fixed #8847, #10370: added some missing methods to MultiValueDict after...

        """Returns a list of (key, list) pairs."""

        return super(MultiValueDict, self).items()

    def iterlists(self):

        """Yields (key, list) pairs."""

        return super(MultiValueDict, self).iteritems()

    def values(self):

        """Returns a list of the last value on every key list."""

        return [self[key] for key in self.keys()]

    def itervalues(self):

        """Yield the last value on every key list."""

        for key in self.iterkeys():

            yield self[key]

    def copy(self):

        """Returns a copy of this object."""

        return self.__deepcopy__()

When a page is requested, Django creates an :class:`HttpRequest` object that

contains metadata about the request. Then Django loads the appropriate view,

passing the :class:`HttpRequest` as the first argument to the view function. Each

view is responsible for returning an :class:`HttpResponse` object.

This document explains the APIs for :class:`HttpRequest` and :class:`HttpResponse`

objects.

HttpRequest objects

===================

        * ``read(num_bytes=None)`` -- Read a number of bytes from the file.

        * ``name`` -- The name of the uploaded file.

        * ``size`` -- The size, in bytes, of the uploaded file.

        * ``chunks(chunk_size=None)`` -- A generator that yields sequential chunks of data.

        * ``chunks(chunk_size=None)`` -- A generator that yields sequential

          chunks of data.

   .. versionadded:: 1.0

   Returns ``True`` if the request was made via an ``XMLHttpRequest``, by checking

   the ``HTTP_X_REQUESTED_WITH`` header for the string ``'XMLHttpRequest'``. The

   following major JavaScript libraries all send this header:

           >>> q.items()

           [('a', '3')]

.. method:: QueryDict.iteritems()

    Just like the standard dictionary ``iteritems()`` method. Like

    :meth:`QueryDict.items()` this uses the same last-value logic as

    :meth:`QueryDict.__getitem()__`.

.. method:: QueryDict.iterlists()

    Like :meth:`QueryDict.iteritems()` except it includes all values, as a list,

    for each member of the dictionary.

.. method:: QueryDict.values()

    Just like the standard dictionary ``values()`` method, except this uses the

           >>> q.values()

           ['3']

.. method:: QueryDict.itervalues()

    Just like :meth:`QueryDict.values()`, except an iterator.

In addition, ``QueryDict`` has the following methods:

.. method:: QueryDict.copy()

['Adrian', 'Simon']

>>> list(d.iteritems())

[('position', 'Developer'), ('name', 'Simon')]

>>> list(d.iterlists())

[('position', ['Developer']), ('name', ['Adrian', 'Simon'])]

>>> d['lastname']

Traceback (most recent call last):

...

>>> d.setlist('lastname', ['Holovaty', 'Willison'])

>>> d.getlist('lastname')

['Holovaty', 'Willison']

>>> d.values() 

['Developer', 'Simon', 'Willison']

>>> list(d.itervalues()) 

['Developer', 'Simon', 'Willison']
