Standalone Mongrel handler Hello World

I think this is the simplest Mongrel handler you can create. It doesn't depend on Rails so this is not what you need to write if you want to install a Rails friendly Mongrel handler.

require 'rubygems'
require 'mongrel'

class HelloHandler < Mongrel::HttpHandler
  def process(request, response)
    response.start(200) do |head,out|
      out << 'Hello World!'
    end
  end
end

h = Mongrel::HttpServer.new("0.0.0.0", "5000")
h.register("/hello", HelloHandler.new)
h.run.join

Notes:

• If you want to output html remember to include head['content-type'] = 'text/html' inside the inner block


• To include static pages you can add h.register("/files", DirHandler.new('.')). After this you can access all files in the current directory through this url http://localhost:5000/files
