module Rainbows
# An optional middleware to proudly display your usage of \Rainbows! in
# the "Server:" response header. This means you can help tell the world
# you're using \Rainbows! and spread fun and joy all over the Internet!

# ------ in your config.ru ------
# require 'rainbows/server_token'
# require 'rack/lobster'
# use Rainbows::ServerToken
# run Rack::Lobster.new
#
# If you're nervous about the exact version of \Rainbows! you're running,
# then you can actually specify anything you want:
#
# use Rainbows::ServerToken, "netcat 1.0"
#
class ServerToken < Struct.new(:app, :token)
# :stopdoc:
#
# Freeze constants as they're slightly faster when setting hashes
