Simple static website in GAE with custom 404 error page

[user2378683 via StackOverflow]

I am using GAE for a simple static website with just html/htm pages, pictures etc. I am also using Python 2.7.

So i use a straight forward app.yaml and main.py and that works. However, when accessing a page which does not exist, it shows a standard 404 page. I want to change that one into custom error page, and tried this below but it does not work.

here are my app.yaml and main.py files:

application: xxxx
version: 11
runtime: python27
api_version: 1
threadsafe: true

default_expiration: "7d"

inbound_services:
- warmup

handlers:
- url: /
  static_files: index.html
  upload: index.html

- url: /(.*)
  static_files: \1
  upload: (.*)

- url: /.*
  script: main.app

Main.py:

import webapp2

class BaseHandler(webapp2.RequestHandler):
  def handle_exception(self, exception, debug):
    # Set a custom message.
    self.response.write('An error occurred.')

    # If the exception is a HTTPException, use its error code.
    # Otherwise use a generic 500 error code.
    if isinstance(exception, webapp2.HTTPException):
      self.response.set_status(exception.code)
    else:
      self.response.set_status(500)

class MissingPage(BaseHandler):
  def get(self):
    self.response.set_status(404)
    self.response.write('Page has moved. Pls look at http://www.yyyyyy.yy to find the new location.')

class IndexHandler(webapp2.RequestHandler):
    def get(self):
        if self.request.url.endswith('/'):
            path = '%sindex.html'%self.request.url
        else:
            path = '%s/index.html'%self.request.url

        self.redirect(path)

    def post(self):
        self.get()

app = webapp2.WSGIApplication(
   [  (r'/', IndexHandler),
      (r'/.*', MissingPage)
      ],
   debug=True)

What is not correct?? I find a lot of entries, but none exactly explains how to do this for a simple website with Python 2.7,

let me know, many thanks, Michael

it looks like it doesn't really need to have any dynamic part of your website except the 404 page. There is an error_handlers can be used directly.
