    Sends the contents of a file to the client. This will use the

    try to use the WSGI server's file_wrapper support.

    By default it will try to guess the mimetype for you, but you can
    also explicitly provide one.  For extra security you probably want
    to send certain files as attachment (HTML for instance).  The mimetype
    guessing requires a `filename` or an `attachment_filename` to be
    provided.

    Please never pass filenames to this function from user sources without
    checking them first.

                     auto detection happens.
    :param as_attachment: set to `True` if you want to send this file with
                          a ``Content-Disposition: attachment`` header.
    :param filename: the filename for the attachment if it differs from the file's filename or
                     if using file object without 'name' attribute (eg: E-tags with StringIO).
