Did I just answer my own question? You need to use the 'wis' handler only when you want to get the entire HTTP request as an InputStream, rather than using the WOMultipartFileIterator to get just the uploaded file content as an InputStream?

This is correct.


So my actual questions are: What is the 'wis' handler for, exactly? When do I need to use it? If I only need to use it when I want to get the entire HTTP Request as a stream (but NOT when I only want to get the uploaded file content as an InputStream).... why would I ever want to do this? What's the point?

Handling a multipart/form-data request has some overhead - in particular, it requires:
1. The client be able to choose a delimiter string that is completely unique within the content (no mean feat if you're talking a gig or so of data).
2. The client be able to properly format a multipart/form-data request.
3. The server parse the incoming request byte by byte looking for the delimiter string.
