Philippe, first sorry for late answer. Time pressures ...

I looked at your code, where you make a subclass of Site where is a test 
form with file input field , then post via streaming to output file.

Problem is that you named file input field as "upload" while in my 
example it is expected to be "file". So, just adjust those two names and 
your example should work.
