How to turn off " Rack::Protection::JsonCsrf"?

Question

In my heroku logs I see this:

 WARN -- : attack prevented by Rack::Protection::JsonCsrf

I know the reason of why it appears there and I want to turn off that protection mechanism. How?

Answer 1

Apply this in an appropriate location such as configu.ru:

configure do
  set :protection, :except => [:json_csrf]
end
