import SocketServer
import BaseHTTPServer
import CGIHTTPServer

class ThreadingCGIServer(SocketServer.ThreadingMixIn,
                   BaseHTTPServer.HTTPServer):
    pass

import sys

server = ThreadingCGIServer(('', 8080), CGIHTTPServer.CGIHTTPRequestHandler)
#
try:
    while 1:
        sys.stdout.flush()
        server.handle_request()
except KeyboardInterrupt:
    print "Finished"

Mixin classes are usually designed to slot right in to an existing
framework. In this particular case, ThreadingMixin needs to be used with
classes which have a certain server structure. It provides methods for your
class which would otherwise be inherited from the later superclasses in the
inheritance list.

If BaseHTTPServer has everything you need, the above solution should be all
you require. If you aren't bothered about interrupting the server you could
just call serve_forever(). I remember when I frist came across the
*HTTPServer classes they seemed a lot more complex than they really are!
