I'm currently drawing a blank as how to get the current browser header information for a user in Python Tornado? For example, in PHP you'd simple view the $_SERVER data. What is Tornado's alternative?

Note: How do I get the client IP of a Tornado request? and the "request" does not work for me.

Here's a snippet based off of a server I have where we retrieve some header data from the request:

class api(tornado.web.RequestHandler):
    def initialize(self, *args, **kwargs):
        self.remote_ip = self.request.headers.get('X-Forwarded-For', self.request.headers.get('X-Real-Ip', self.request.remote_ip))
        self.using_ssl = (self.request.headers.get('X-Scheme', 'http') == 'https')
    def get(self):
        self.write("Hello " + ("s" if self.using_ssl else "") + " " + self.remote_ip)
