:nut_and_bolt: Utility belt for the HttpHeader libraries


Add this line to your application's Gemfile:

gem 'http_headers-utils'

And then execute:

$ bundle

Or install it yourself as:

$ gem install http_headers-utils

This can be used for almost any header that allows multiple values, as per the RFC these are consistent with the exception of the Cookie / Set-Cookie headers (at time of writing).

require 'http_headers/utils/list'

class ListBasedHeader < Utils::List
  def initialize(value)
    super value, entry_klazz: Entry

  class Entry
    def initialize(value, index:, parameters:)
