Access the channel from a http.Request instance in Twisted

Question

I'm working on a project that uses the Twisted web facilities, but not the high-level web framework. How can I get access to the HTTPChannel instance (the twisted protocol) that created a certain http.Request instance?

I see that the constructor of http.Request has the channel as an argument, but there is not method/property that further accesses it.

Also, while I can access the HTTPFactory instance from the channel via the factory property - can i access the factory directly from the request instance?

It looks like the channel is available directly on the Request. Consider Request.__init__:

def __init__(self, channel, queued):
    """                                                                                                                                     
    @param channel: the channel we're connected to.                                                                                         
    @param queued: are we in the request queue, or can we start writing to                                                                  
        the transport?                                                                                                                      
    """
    self.notifications = []
    self.channel = channel
    self.queued = queued
    ...

self.channel = channel seems to be just what you're looking for.
