Of course I dont know anything about your protocol, but anyways:

If Content-Length is the last header

Mhm rather something like, since you don't know the chunk size:

    def rawDataReceived(self, data):
    	datalen = len(data)
	if self.body_length > datalen:
	    self.body_length -= datalen
	    do_something_with(data)
	else:
	    part = data[:self.body_length]
	    extra = data[self.body_length:]
	    do_something_with(part)
	    self.setLineMode(extra=extra)


cheers,
peter.
