I'm still a little new to Twisted, so I was wondering if some kind soul might be willing to help make sure I'm looking at things correctly. First, I think I understand the difference between protocol factories and protocols, but I could use a little reassurance. My current understanding is that the protocol factory holds the state that is common to all connections, whereas the protocol holds the state that is specific to a particular connection. Is that an accurate understanding? If that is correct, then what is the difference between a protocol factory and a protocol for a client (like HTTPClient) where only one connection is involved? I'm a bit confused about why HTTPClientFactory isn't a trivial class. According to my current understanding, all of the logic would be in HTTPClient. I was also confused about why HTTPClientFactory would set `self.protocol.followRedirect = followRedirect` in its __init__ method. Since `self.protocol` is the HTTPPageGetter class, it appears that the client factory is setting the followRedirect attribute for all connections (associated with all HTTPClientFactories). I was surprised that HTTPClientFactory wouldn't set `self.followRedirect = followRedirect`, in which case HTTPClient would look at `self.factory.followRedirect`. If someone could help clear up these questions for me, I feel like I would understand Twisted a lot better.
