Sending the swf file as you did in other email isn't probably of any
use.
We need to get what is actually received by the handler itself so we
can send that through the util.FieldStorage class to test it. This is
what
the handler I sent below was about. Note though the small change I
marked against the code below. Don't forget to change the save path to
something meaningful.
Put the code in a file called grabinput.py in your directory:
c:/Program Files/Apache Group/Apache2/htdocs/python
and change:
PythonHandler mod_python.publisher
to:
PythonHandler grabinput
in your config.
It is the file that the upload data is saved into that we would need not
the original swf file.

This possible should be:
data = open("/some/path/post.dat", "wb")
Ie., use binary mode to ensure that \r\n sequences are maintained as is.
This may not be an issue on Win32, but might be still good to do it.
