Can i inherit the twisted.web.http.Request.requestReceived ??

In the comment, said that "This method is not intended for users".
I has inherited the rawDataReceived and it like this:

def rawDataReceived(self, data):
        self.resetTimeout()
        if len(data) < self.length:
            self.requests[-1].content.send(data)
            self.length = self.length - len(data)
        else:
            self.requests[-1].content.send(data[:self.length])
            self._finishRequestBody(data[self.length:])

the "self.requests[-1].content.send(data)" will send the data in another http connection. In fact, i use the httplib here.
All goes well, but it doesn't work at the last step in allContentReceived. And it's req.requestReceived(command, path, version).

So can i inherit this method requestReceived. Or where is it go wrong?

my code is here. You can download it.
