Sorry my VPS has been down for quite
some time today :/ Not happy!

Here is the sample:

<code>
#!/usr/bin/env python
# -*- coding: utf-8 -*-
# vim: set sw=3 sts=3 ts=3

import optparse

from pymills import event
from pymills.event import manager
from pymills.net.sockets import TCPServer
from pymills.event.core import listener, Component
from pymills.net.http import HTTP, Response, Dispatcher
from pymills import __version__ as systemVersion

USAGE = "%prog [options] [path]"
VERSION = "%prog v" + systemVersion

###
### Functions
###

def parse_options():
   """parse_options() -> opts, args

   Parse any command-line options given returning both
   the parsed options and arguments.
   """

   parser = optparse.OptionParser(usage=USAGE, version=VERSION)

   parser.add_option("-b", "--bind",
         action="store", default="0.0.0.0:8000", dest="bind",
         help="Bind to address:port")

   opts, args = parser.parse_args()

   return opts, args

###
### Components
###

class Test(Component):

   channel = "/"

   @listener("index")
   def onINDEX(self, request, response):
      self.send(Response(response), "response")

   @listener("hello")
   def onHello(self, request, response):

      if request.cookie.get("seen", False):
         response.body = "Seen you before!"
      else:
         response.body = "Hello World!"
         response.cookie["seen"] = True

      self.send(Response(response), "response")

   @listener("test")
   def onTEST(self, request, response):
      response.body = "OK"
      self.send(Response(response), "response")

class WebServer(TCPServer, HTTP): pass

###
### Main
###

def main():
   opts, args = parse_options()

   if ":" in opts.bind:
      address, port = opts.bind.split(":")
      port = int(port)
   else:
      address, port = opts.bind, 80

   server = WebServer(port, address)
   dispatcher = Dispatcher()

   event.manager += server
   event.manager += Test()
   event.manager += dispatcher

   while True:
      try:
         manager.flush()
         server.poll()
      except KeyboardInterrupt:
         break

###
### Entry Point
###

if __name__ == "__main__":
   main()
