[mod_python] POSTed form fields?

In other words, something like:

import cgi

len = int(req.headers_in["content-length"])
form_data = cgi.parse_qs(req.read(len))

Should do it. Dr. Timouchouk is right - if you're POSTing large files
(50K+), then you should check the size returned by read() and read() again
if it wasn't all.

The next release will make this unnecessary - read() will return all there
was to read. It will also follow the apache Timeout directive.

If you're handy with CVS - you can get that code right now from the
sourceforge CVS server.
