Fixed #8546 -- Fixed error in request-response.txt where we were incorrectly...

There's nothing Django-specific about the ``Content-Disposition`` header, but

it's easy to forget the syntax, so we've included it here.

Attributes

----------

.. attribute:: HttpResponse.content

    A normal Python string representing the content, encoded from a Unicode

    object if necessary.

Methods

-------

    values you used in ``set_cookie()`` -- otherwise the cookie may not be

    deleted.

.. method:: HttpResponse.content()

    Returns the content as a Python string, encoding it from a Unicode object

    if necessary. Note this is a property, not a method, so use ``r.content``

    instead of ``r.content()``.

.. method:: HttpResponse.write(content)

    This method makes an :class:`HttpResponse` instance a file-like object.
