This IS possible, but you'll have to do some work.
I assume this is a CGI script, and that you're using cgi.FieldStorage() to
fetch the POST contents. The key problem for you is that
cgi.FieldStorage() (and, more specifically, cgi.FieldStorage.read_binary)
does not return until the entire transmission is complete.
Now that you know that, your path should be clear: all you need to do is
make your own custom version of FieldStorage that updates a status variable
somewhere. Piece of cake!
