With haproxy 1.5, Is there any way to add a dynamic header to the http response (like the `http-request add-header` option for request headers)? I'm adding a X-Request-Id header to requests before forwarding them on to the back end, but would also like to be able to send this same header back in the response to the client. Something like the `http-request add-header` or `unique-id-header` options would be great. The former might be more flexible as it can be used for other things, but the latter would also work.
Reading through the docs I don't see any way this could be done. If not can it be a feature request? Thanks -Patrick
