Answer 1

You can use logic similar to tornado/httpserver.py or just create tornado.httpserver.HTTPServer() with xheaders=True.

# Squid uses X-Forwarded-For, others use X-Real-Ip
ip = self.headers.get("X-Forwarded-For", self.remote_ip)
ip = ip.split(',')[-1].strip()
ip = self.headers.get(
    "X-Real-Ip", ip)
if netutil.is_valid_ip(ip):
    self.remote_ip = ip
# AWS uses X-Forwarded-Proto
proto = self.headers.get(
    "X-Scheme", self.headers.get("X-Forwarded-Proto", self.protocol))
if proto in ("http", "https"):
    self.protocol = proto
