-By default, all methods can only be used by users logged into OpenERP (OpenERP uses cookies to track logged users).

+There are some cases when the current user is not relevant, and we just want to give access to anyone to an URL. A
+typical example is be the generation of a home page for a website. The home page should be visible by anyone, whether
+they have an account or not. To do so, add the ``'admin'`` value to the ``auth`` parameter of ``http.route()``:
