[web2py] Routes.py not working when deployed to GAE

[Dane]

Hello,

In my routes.py file, I have this line:

routes_in = (('.*:/crossdomain.xml', '/init/static/crossdomain.xml'),)

Working locally, if I go to http://localhost:8080/crossdomain.xml ,
the file is there.

However, when I upload to google app engine, 
http://www.mydomain.appspot.com/crossdomain.xml
gives a 404. The rest of the deployed app is working fine.

Any ideas?

Thanks,

Dane
