Hi Willy, I'm trying to do a similar thing where I'd like to be able to return the contents of a request header in a response header (like the way the CORS Access-Control-Allow-Headers response header might contain the list of headers given in Access-Control-Request-Headers). Is this possible at all as of the new work that's been done in v1.5? Thanks, Matthew
