Right now I wanted to write a practice program that just dumps the text in the file to a webpage, but eventually I would like to manipulate the data in the file someway and output something different. I am certain my html is fine... I have:
> <form action='upload.py' method='post' enctype='multipart/form-data'>

> Originally I tried using the publisher handler, so my "action" was pointing to a different file and method that handles the request. To access the FieldStorage object I used req.form. But to correspond to the html above, I made "upload" my PythonHandler and created my own FieldStorage object as follows:
> def handler(req):
>     fields = util.FieldStorage(req)
>     f = fields['input_file']

Could there still be a problem witht the __getitem__ method or the FieldStorage not being able to recognize the mime type (although the documentation states this problem has been fixed).
