the handler object is looked up from this module.
By default, this module will handle files with the extensions `.wsgi'
-or `.wsgi2' using the `chain' handler, which chainloads such files and
+or `.wsgi3' using the `chain' handler, which chainloads such files and
runs them as independent WSGI applications. See its documentation for
details.
