BTW - you don't need to use twisted.web.server.Request - since the refactor to HTTP you only need twisted.protocols.http.Request, no need to use twisted.web unless you are using it as a web framework.

Actually you don't need to use Request at all. If you want this to work with other twisted.web servers, it would be best to structure your work as additions to Resource, not Request.

What functionality are you adding at the Request level?

I'm not really adding any functionality. I was merely making a previous Twisted/Quixote script work with Twisted-0.18.0, which is how I found the reported problem. This script is so short I include it here. Jon """qserv Demo of an HTTP server built on top of Twisted Python that serves a Quixote application, and also supports an SMTP interface.
