> And another one from @chrismccord himself: you could make a plug that calls the Plug.Session init, at runtime plug MySession, ... defmodule MySession do def init(opts), do: Plug.Sesson.init(opts) def call(conn, opts) do runtime\_opts = Keyword.put(opts, :domain, ...) Plug.Session.call(conn, runtime\_opts) end end in this case, I kept init at compiletime, but modified the options before calling the session plug, to do as much work as possible at compile time but you get the idea?…
