Google App Engine Python WebApp framework supported self.error() codes

I know we can return errors to requests by calling self.error(http_error_code_here). However, there are some error codes that don't seem to be supported. "Unsupported error code" comes out when I use error code 510.

I used http://en.wikipedia.org/wiki/List_of_HTTP_status_codes as a reference for the error codes I am using.

What http error codes are curre开发者_高级运维ntly supported by the GAE Python WebApp Framework?

You'll find the supported status codes in

google_appengine/google/appengine/ext/webapp/__init__.py

around line 270.
