Просто выключите сервер, после чего второй файл подается.Вот пример :
server.rb
require 'webrick'
server = WEBrick::HTTPServer.new :Port => 8000, :DocumentRoot => '/'
server.mount_proc '/' do |req, res|
# response with simple html body
res.body = '
<html>
<head>
<title>My Webpage</title>
<!-- first file -->
<link rel="stylesheet" href="/one_file.css" type="text/css">
<!-- second file -->
<link rel="stylesheet" href="/second_file.css" type="text/css">
</head>
<body>
<h1>Hello world!</h1>
</body>
</html>'
end
server.mount_proc '/one_file.css' do |req, res|
res.body = 'h1 { color: blue; }'
end
server.mount_proc '/second_file.css' do |req, res|
res.body = 'h1 { color: red; }'
puts "Shutdown server !"
server.shutdown
end
server.start
Запустите server.rb:
$~ ruby server.rb
