[undertow-dev] AuthenticationMechanism, ChallengeResult and Response Code

Hi, I am wondering if a flag can be set in ChallengeResult such that undertow does not try to set the response code on the httpserverexchange before sending the challenge? The reason is that an authentication mechanism may have already utilized the httpservletresponse object to set a response code such as: =========== response.setStatus(HttpServletResponse.SC_MOVED_TEMPORARILY); response.sendRedirect(destination); ============== Now since undertow tries to set a response code on the httpServerExchange, there is an error.
