Not true. The cgi module recognizes and makes available all parameters
which come back from the form, and hidden values are sent back from the
form like any other parameter.
If a form has a field like this:
<INPUT TYPE=hidden NAME=user VALUE=xxx>
then when your python script is invoked, you can get at the value like
query = cgi.parse()
user = query['user'] #First and only element on the list
user = None # or whatever ...
