module ActionController
  module Head
    # Returns a response that has no content (merely headers). The options
    # argument is interpreted to be a hash of header names and values.
    # This allows you to easily return a response that consists only of
    # significant headers:
    #
    #   head :created, location: person_path(@person)
    #
    #   head :created, location: @person
    #
    # It can also be used to return exceptional conditions:
    #
    #   return head(:method_not_allowed) unless request.post?
    #   return head(:bad_request) unless valid_request?
    #   render
    #
    # See +Rack::Utils::SYMBOL_TO_STATUS_CODE+ for a full list of valid +status+ symbols.
