How to receive multiple responses from just one request?

Hi all,

I'm working with __superagent__ in a personal project and am implementing an _API method_ that executes a _long process_. I send _response messages_ every iteration of the process to inform the client but I'm not able to update the browser with the proper information until the end of the process when response ends that shows all messages.
I would like to know if superagent library is able to do this kind of stuff.

As a background, I'm developing my API in node.js and send iterative messages with `res.write()` method under Express web server.
