crossdomain.xml

[Jacob Feisley]

We are developing Flash applications that connect to a service on App
Engine, however, when we upload the crossdomain.xml file to the site
it is not always rendered properly. The issue appears to stem from
using our own domain through Google Apps.

This URI will get the proper cross domain file that was uploaded:
http://pyamf.appspot.com/crossdomain.xml

However, this URI retrieves a crossdomain file that is incorrect. My
theory is that the redirect from Google Apps is somehow mucking with
things:
http://ae.pyamf.org/crossdomain.xml

Thanks for any insight you can provide.

I'd guess you're right.

Taking a quick look at the headers between the two links (a la
Firefox):

Through the redirect, the front end is serving something very
different. Different Content-Type, gziped, etc.

I don't have an AppEnging account, or I'd test a bit more. But that's
likely the problem right there.

Yea, we have it working! We have a basic echo test working at the
moment and I am currently adapting some of our other examples to the
App Engine api.

You can see our ongoing work here: http://pyamf.org/wiki/GoogleAppEngine
And our sample site is http://ae.pyamf.org

Hey Jacob,

Any updates on the crossdomain.xml issue? Did you file a bug?

Thanks,
Aral

I've opened this as http://code.google.com/p/googleappengine/issues/detail?id=266

[Meaglith Ma]

Using a crossdomain.py export the content of crossdomain.xml, and add
the url in the app.yaml:
- url: /crossdomain.xml
script: crossdomain.py
