Top Most Reading parameters from a multipart/form-data upload form

That is, given the form:

      ENCTYPE="multipart/form-data"
      METHOD=POST>

What is your name? 


What file are you sending? <INPUT TYPE=FILE NAME=secretDocument>

I cannot read the submitter using request.getParameter("submitter") (it returns null). Ans:2.
