I am sometimes using stream=True and then consuming the raw response chunk by chunk. I if dump one of those responses using toolbelt's dump(), it consumes all the content and later processing fails because the download stream is now gone and closed.

As for outgoing request data, when a file-like payload is used the body is not dumped, for response bodies this should be achievable too, dumping only the headers.

It appears to me that there is no way to tell that a response is being streamed from the response object itself, so an optional parameters would be needed on dump (I might be wrong).
