---------------------------------

We are reviewing for a possible low risk solution for this issue, hopefully we can get something in for 3.3.3, but we are not sure atm.

> It seems the Filter currently tries to reformat the response in any case. But if you e.g. get a HTTP 304 response, this doesn't even have a content body (onyl headers) and wrinting to the response causes an Exception:
