@sixofhearts You can always extend the multi-method handler/sync-default to support your own custom keyword responses. Or possibly mix the response headers in, in a middleware afterwards — depending of course on exactly what you need to do.

Ah, thanks @rickmoynihan I think my case calls for extending handler/sync-default - good call

This may well be more of an ataraxy question than duct as such but I'll ask anyway... Is there any way of explicitly specifying the order in which middleware for a specific route is applied? So for example, if I have this very contrived config:

{:duct.router/ataraxy
 {:routes     {"/my/route"
               {:get ^{:aaa-middleware {:args :whatever-aaa}
                       :bbb-middleware {:args :whatever-bbb}}
                     [:my/handler]}}
  :middleware {:aaa-middleware #ig/ref :middleware/aaa
               :bbb-middleware #ig/ref :middleware/bbb}}}
