-``delete_cookie(key)``
+``delete_cookie(key, path='/', domain=None)``
     Deletes the cookie with the given key. Fails silently if the key doesn't
     exist.
 
+    The ``path`` and ``domain`` arguments are new in the Django development version.
+    Due to the way cookies work, ``path`` and ``domain`` should be the same
+    values you used in ``set_cookie()`` -- otherwise the cookie may not be deleted.
+
 ``content``
     Returns the content as a Python string, encoding it from a Unicode object
     if necessary. Note this is a property, not a method, so use ``r.content``
