Created Issue: Tweaks and the HttpContextAdapter [14861]

I believe that all of these classes could use a little tweaking in certain areas. For instance the HttpContextAdapter automatically calls to the worker function. There should be a way for the HttpContextAdapter to be given an alternate WorkerFunction. With the current pattern certain things seem fixed and would require a high level of expertise or reverse engineering to change at run time when in fact I can simplify this very easily through members such as properties. I would even be able to utilize a dynamically created action to complete the logic required. It is almost infinite of one and infinite of another.

Please post your opinions here and I will try to deal with them in relation to 'tweaks' et al.
