How to write a non blocking SimpleHTTPRequestHandler ?

[yacinechaouche at yahoo.com]

I wrote a little script that acts like a proxy, you just give it a URL and it will fetch the content and display it back to you. 

For some reason, this proxy blocks sometimes and refuses to serve any new queries. The script still runs, but it seems like it's stuck somewhere.

When I strace it to see what it's doing, I find it hanging on this instruction : 
root at backup[10.10.10.21] ~/SCRIPTS/INFOMANIAK # strace -fp 6918
Process 6918 attached - interrupt to quit
recvfrom(6,
^CProcess 6918 detached
root at backup[10.10.10.21] ~/SCRIPTS/INFOMANIAK # 

I read in the SimpleHTTPServer source code that one can inherit from the SocketServer.TrheadingMixIn mixin to enable a threaded server to handle multiple requests at a time instead of just one (thinking maybe that's what was blocking it). However, it seems like it has nothing to do with my problem. What I need to do is not only handle multiple requests at a time, but more importantly to make the request handler non-blocking.

Any ideas ? here's come code : 

import SimpleHTTPServer
import BaseHTTPServer
import SocketServer
import requests

class Handler(SocketServer.ThreadingMixIn,SimpleHTTPServer.SimpleHTTPRequestHandler):
    def do_GET(self):
        self.send_response(200)
        self.send_header('Content-Type', 'text/html')
        self.end_headers()
        # self.path will contain a URL to be fetched by my proxy
        self.wfile.write(getFlux(self.path.lstrip("/")))

session = requests.Session()
IP,PORT = "MY_IP_HERE",8080

def getFlux(url):
    response  = session.get(url)
    s = response.text
    return s

server = BaseHTTPServer.HTTPServer((IP,PORT),Handler)
server.serve_forever()

Thank you.
