Appengine 1.6.3 Python 2.7 - Error 404

[andidol]

Hi,

I just migrated my AppEngine App to 2.7 and concurrent requests. Everything works except some requests response with a 404 Not Found (The resource could not be found.) Google Frontend Server error. 

What is going on here? It works the most time but sometimes requests get a 404 response from my app. The URL definitely exists and should get handled as it does 90% of the requests.

Are there limitations on an instance which returns 404 if I go beyond them?

Thank you

There shouldn't be. If you go over quota GAE should return a 503 error.

This is a long shot, but any chance you have accidentally enabled traffic splitting? This is a new feature that allows you to very easily do A/B testing:

Anyone else seeing similar problems?

Excellent feature! Is routing to non appspot.com domains supported?

Does traffic split versions share MemCache?

Hi, I found out what the problem is. I have %0A (carriage return) in the URL and since the new version python2.7/webapp2 the URL no longer matches anything..

- url: /v1.*

  script: ...

http://<baseurl>/v1/lorem%0Aipsum => does not work, but worked before the migration. I get an "Error 404. resource not found" result page. 

I don't get an Not found error: ... did not match any patterns in application configuration.

How could I solve/workaround this?

Thank you

Solved it with using additional specifying the %0A (\n) in the regular expression. In old webapp it was not necessary.

- url: /v1.*

  script: ..

application = webapp2.WSGIApplication([(r'/v1/(.|\n)*', Script)], debug=True)

Split versions do share MemCache.
