People need to be able to inject behavior on responses before things are returned to the caller to handle things like retry, redirect, etc...
Review the design guidance

We probably need to model:

• ResponseInfo (abstract reflection of http response)
• RequestMiddleware (interface for middlewares excuting before the request is sent)
• ResponseMiddleware (interface for middlewares executing after the response is received)
• A property bag to tag the request with options for the middleware
• A way to register (and order?) middlewares
• A way to set default options for requests
