I want enable my clojure web app to accessed in a iframe. How do i unset the X-Frame-Option Header ? Any ideas . Is it here https://ring-clojure.github.io/ring-headers/ring.middleware.x-headers.html#var-wrap-frame-options

it's set by ring-defaults here https://github.com/ring-clojure/ring-defaults/blob/16aaff02e58e4d839549fdcdbb510b9228a7eea4/src/ring/middleware/defaults.clj#L48

so you'd want to update site-defaults with (assoc-in site-defaults [:security :frame-options] {:allow-from uri}) where uri is the URI you're calling the app from
