[Zope-dev] REQUEST object -> where's the body?

I'd like to get the body from a HTTP Request ( method="POST" ) ( I'm trying to submit data but not with a browser...) Can anybody tell me how to get the body? I'm trying to set the request like this: req.putHeader("Content-Length",str(len(some_string)) ) req.endHeaders() . . req.send(some_string) thanks Mike
