Hi Daniel,
Thank you so much for your suggestion. I am quite new to python and
twisted so I am not very certain about how to make it work well. Does that
mean if I change the dataReceived by adding a line to instantiate the
MultiEchoFactory like this, it will work?
def dataReceived(self, data):
"As soon as any data is received, write it back."
handlesendermessage = self.factory.app.handle_message(data)
if handlesendermessage:
self.transport.write(data)
MultiEchoFactory()
MultiEcho().dataReceived(data)
