Unfortunately it is now showing up in REQUEST.form, it is not a POST like what 
you get with a file upload from a form. Zope is showing that the correct size 
of data was sent to that page.

It was not sent with that kind of encoding at least not in any way I can tell. 
It was a webcam and all I could give it was a url to POST the data to and it 
did not submit it like a regular form.
