Dear List:
I am having a heck of a time trying to figure out why this
traceback is happening, and I was hoping that you could shed some
light on the situation. I am sorry for bothering you with this
simple thing, but I can't seem to figure it out!
No need to apologize, however twisted-web is a better list for this
question.

exceptions.TypeError: html is not a resource or a response
this exception usually indicates that a render method didn't return
an IResponse object but instead returned a string (or none.) The
above code did not include anything that implemented IResource.

This might have something to do with the fact that you're calling
writeResponse.
You should never call writeResponse directly on a request object.
You should _return_ an IResponse or a deferred which results in an
IResponse from an IResource's render method._______________________________________________
