I am wondering if it is possible to access the body of a response in modifyResponse? I am working on overriding ServantErr's so I can respond with a more informative json response. I have it all working other then accessing the body to get the current error message and reuse.

Many middlewares modify the response body, such as the gzip middleware. The tricky case to deal with is streaming responses, but it can certainly be done.

Thanks Michael, I found a solution that works for me. I will post it back later in case anyone else finds this thread.
