-    Returns ``True`` if the request was made via an ``XMLHttpRequest``, by
-    checking the ``HTTP_X_REQUESTED_WITH`` header for the string
-    ``'XMLHttpRequest'``. Most modern JavaScript libraries send this header.
-    If you write your own ``XMLHttpRequest`` call (on the browser side), you'll
-    have to set this header manually if you want ``is_ajax()`` to work.
-
-    If a response varies on whether or not it's requested via AJAX and you are
-    using some form of caching like Django's :mod:`cache middleware
-    <django.middleware.cache>`, you should decorate the view with
-    :func:`vary_on_headers('X-Requested-With')
