Because, as the traceback tells you, visitor is None. As you said, the
cookie is not recognized. Try inserting the following line at the top
of your script:

print "Content-type:text/html\r\n\r\n", os.environ.get('HTTP_COOKIE',
'NO COOKIE DATA')

That should give you the value of the cookie, which might help you
debug why it is not being loaded.
