Is the preferred way to wrap middleware in untangled to use set-pre-hook! ?

it is, but note that you generally want to get-pre-hook and then compose in the handlers you want and set-pre-hook (let [pre-hook (.get-pre-hook handler)] (.set-pre-hook! handler (comp pre-hook some-handler))

There’s also fallback-hook, you can see the handler stack here: https://github.com/untangled-web/untangled-server/blob/master/src/untangled/server/impl/components/handler.clj#L146

@adambros: Thanks!
