    Serve static files below a given point in the directory structure.

    To use, put a URL pattern such as::

        from django.views.static import serve

        path('<path:path>', serve, {'document_root': '/path/to/my/files/'})

    in your URLconf. You must provide the ``document_root`` param. You may
    also set ``show_indexes`` to ``True`` if you'd like to serve a basic index
    of the directory.  This index view will use the template hardcoded below,
    but if you'd like to override it, you can create a template called
    ``static/directory_index.html``.

      This is the value of the If-Modified-Since header.  If this is None,
      I'll just return True.
