Order of route hanlder call and on_data

[luxapana]

Hi
I see that onData is defined in HttpResponse class which seem to get called to stream the body of the request. Please confirm if this is correct?

Based on some of the tests I did it looks like the route handler is called first, followed by onData (maybe multiple times). Can I assume that this is the case always - for different http methods/routes?

Also please confirm that I can use the content-length header to check if there is a body or not in the request or is there a built-in method that I can use?

Thanks
