I don't see anything in that page that changes what I am doing. I can get
rid of everything that has to do with retrieving data from
cgi-FieldStorage, and the code executes fine although I get a blank page.
I have revised the code somewhat, but the initial problem of
cgi.FieldStorage being empty is still there. I don't get an error now,
just an empty page. Here is the revised code:

 #! /usr/bin/python
print "Content-Type: text/html\n\n"
print
print "<html><head></head><body>\n\n"

import cgitb, os, sys
cgitb.enable()
sys.strerr = sys.stdout

import cgi

form = cgi.FieldStorage()
field_list = '<ul>\n'
for field in form.keys():
    field_list = field_list + '<li>%s</li>\n' % field
field_list = field_list + '</ul>\n'
print field_list
print "</body></html>\n\n"
