# DefaultType: the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, “text/plain” is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use “application/octet-stream” instead to
# keep browsers from trying to display binary files as though they are
# text.
DefaultType text/plain
