I need to make a .data file available through a URL. Locally, this works perfectly, the app.yaml simply contains

```
- url: /dev
  static_dir: dev/

```

and everything in that folder is served correctly, .data .js and .html

On the server, the .data file is inaccessible. I've even tried specifically mentioning the files name

```
- url: /dev/WebGL/Release/WebGL.data
  mime_type: text/plain
  static_files: dev/WebGL/Release/WebGL.data
  upload: dev/WebGL/Release/WebGL.data

```

and it still won't serve.
you can see it live here

[tbc-pre-alpha.appspot.com/dev/WebGL/Release/WebGL.data](http://tbc-pre-alpha.appspot.com/dev/WebGL/Release/WebGL.data) <- inaccessible

[tbc-pre-alpha.appspot.com/dev/WebGL/Release/WebGL.js](http://tbc-pre-alpha.appspot.com/dev/WebGL/Release/WebGL.js) <- accessible

there's another file WebGL.html.mem that's not working for the same reasons

any help's much appreciated. thanks!
