Why doesn't the cache-control value update in Elixir/Phoenix 1.2?

I have a JSON api setup via Phoenix 1.2....

In router.ex, I pipe my JSON endpoints thru pipeline as follows:

pipeline :api do
    plug :accepts, ["json"]
  end

Whne I try and add a cache-control value to the response headers in the JSON response I send back to my browser making the request to the GET endpoint via:

  conn
  |> put_resp_header("cache-control", "max-age=2000")

I don't see that the cache-control has been updated...

req_headers: [{"host", "localhost:4000"}, {"connection", "keep-alive"},               
  {"cache-control", "max-age=0"}, {"upgrade-insecure-requests", "1"},  
...

You mixed up things. If you want to have it as a response header, check the resp_headers, not req_headers. Otherwise - you should use Plug.Conn.put_req_header/3 and not put_resp_header.
