List of available Rails http headers (like ":success", ":created", and ":bad_request"). Where is it?

Question

You can use head to build header-only responses. The Rails guide is very helpful in pointing out that you can send a :bad_request or :created header. Where is a list of all of these Rails HTTP header aliases?

Answer 1

Have a look at Rack::Utils::HTTP_STATUS_CODES, it's used by Rails to set the status codes. To have the symbol, just "downcase" and "underscore" the hash values.
