Multithreaded web server in python

Question

I'm trying to create multithreaded web server in python, but it only responds to one request at a time and I can't figure out why. Can you help me, please?

#!/usr/bin/env python2
# -*- coding: utf-8 -*-

from SocketServer import ThreadingMixIn
from  BaseHTTPServer import HTTPServer
from SimpleHTTPServer import SimpleHTTPRequestHandler
from time import sleep

class ThreadingServer(ThreadingMixIn, HTTPServer):
    pass

class RequestHandler(SimpleHTTPRequestHandler):
    def do_GET(self):
        self.send_response(200)
        self.send_header('Content-type', 'text/plain')
        sleep(5)
        response = 'Slept for 5 seconds..'
        self.send_header('Content-length', len(response))
        self.end_headers()
        self.wfile.write(response)

ThreadingServer(('', 8000), RequestHandler).serve_forever()

Check this post from Doug Hellmann's blog.

from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler
from SocketServer import ThreadingMixIn
import threading

class Handler(BaseHTTPRequestHandler):

    def do_GET(self):
        self.send_response(200)
        self.end_headers()
        message =  threading.currentThread().getName()
        self.wfile.write(message)
        self.wfile.write('\n')
        return

class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    """Handle requests in a separate thread."""

if __name__ == '__main__':
    server = ThreadedHTTPServer(('localhost', 8080), Handler)
    print 'Starting server, use <Ctrl-C> to stop'
    server.serve_forever()
