[undertow-dev] AuthenticationMechanism, ChallengeResult and Response Code

[Anil Saldhana]

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.

Regards,
Anil
