Add "Content-Length" in HTTP header response?

[ghost]

Maybe I missed something, it seams there is no Content-Length field in the response. I'd like to know if it's possible to do that. IMO it can be usefull when you deal with big json files, so you can calculate a % download progress,

Thanks!

Not sure if this is a good way to do that. Would be nice if someone can review this.

In ressource.py, I've added at the end of create_response(...)

...
response = response_class(content=serialized, content_type=build_content_type(desired_format), **response_kwargs)
response['Content-Length'] = len(serialized)
return response

Django has content-length middleware http://stackoverflow.com/questions/5554952/how-do-i-get-the-content-length-of-a-django-response-object
