Not enough information here to say for sure, but be aware that you can
only create one instance of FieldStorage per request, as the body of the
request gets "consumed". So if you do something like:
form1 = FieldStorage(req)
form2 = FieldStorage(req)
form1 will be populated with the contents of the POST but form2 will not.
When the FieldStorage instance is being created it will always parse the
query string so you will always get those fields for a GET. For POST,
the form data is encoded in the body of the request which FieldStorage
treats as a file stream and creating form1 reads to the end of the
stream. When you create form2, you are already at the end of the stream,
so there is nothing to process.
Note that publisher automatically creates a FieldStorage instance as
req.form. If you are using publisher, don't create your own instance.
Use the one stuffed into req.form.
