Asynchronous programming with Tornado

Asynchronous programming can be tricky for beginners, therefore I think it's useful to iron some basic concepts to avoid common pitfalls.

For an explanation about generic asynchronous programming, I recommend you one of the [many][2] [resources][3] [online][4].

I will focus on solely on asynchronous programming in [Tornado][1]. From Tornado's homepage:

Put a closure on it

Sometimes you'll have objects that manage state along with event handling. This happens frequently in MVC apps. Let's start with a messy example:

    def get(self, file_name):
        _file_dir = os.path.abspath("")+"/my/path/downloads"
        _file_path = "%s/%s" % (_file_dir, file_name)
        if not file_name or not os.path.exists(_file_path):
            raise HTTPError(404)
        self.set_header('Content-Type', 'application/force-download')
        self.set_header('Content-Disposition', 'attachment; filename=%s' % file_name)
