ring.util.response/header seems to take one header (key value). Whats the way to add multiple at once?
Make the value a collection. e.g. {"X-Foo" ["bar" "baz"]}
ah.
hmm it looks like you can just assoc in (assoc-in
(handler request) [:headers <header>] <value>))`
I mean, thats just what the header function does. i dont know what i expected.
