http server whit proxy

[jrcruz]

Im tying to implement an httpserver for handling request and i want that request passe to another url behind proxy, so far i got this code.

import requests
import http.server
import socketserver


url = 'http://live.impresa.pt/live/sic/sic540p.m3u8'

proxies = {

    'https': 'http://80.211.204.126:443'
}
r = requests.get(url,proxies=proxies)



 class myHandler(http.server.SimpleHTTPRequestHandler):
  def do_GET(self):
    if self.path == '/sic':
        self.send_response(307)
        new_path = r.url
        self.send_header('Location', new_path)
        self.end_headers()

port = 9999
Handler = myHandler
webserver = socketserver.TCPServer(("10.0.0.110",port),Handler)
print ("Python web server ok")
webserver.serve_forever()

when i try acess 10.0.0.110:9999/sic the url is not passing to the proxy and came direct, how can i change this for the request is made behind proxy?
