Ruby-on-rails – Purpose of “consider_all_requests_local” in config/environments/development.rb


What is the purpose of this Rails config setting…

Non-local requests result in user-friendly error pages. Local requests, assumed to come from developers, see a more useful error message that includes line numbers and a backtrace. consider_all_requests_local allows your app to display these developer-friendly messages even when the machine making the request is remote.
