 here's a more complete and bug-free version of the example
 in the library reference.  you'll find more examples examples
 (including improved http client classes) in the eff-bot guide.

 import asyncore, socket

 class http_client(asyncore.dispatcher):

     def __init__(self, host, path):
         asyncore.dispatcher.__init__(self)
         self.path = path
         self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
         self.connect( (host, 80) )
         self.buffer = 'GET %s HTTP/1.0\r\n\r\n' % self.path

     def handle_connect(self):
         pass

     def handle_read(self):
         data = self.recv(8192)
         print data

     def handle_close(self):
         self.close()

     def writeable(self):
         return (len(self.buffer) > 0)

     def handle_write(self):
         if self.buffer:
             sent = self.send(self.buffer)
             self.buffer = self.buffer[sent:]

 c = http_client("www.python.org", "/index.html")

 asyncore.loop()
