Darran Lofthouse commented on ELY-1689:
---------------------------------------

May delay this one whilst looking at alternative issues, one issue here is we want the responders to be called in the same order the mechanisms were originally called this is especially important if mechanisms are adding the same headers where header ordering can have meaning.
