Very Simple Rack TryStatic

TryStatic

require 'rack'

class MyApp
  def call env
    [200, {"Content-Type" => "text/html"}, ["Hello Rack Participants"]]
  end
end


class TryStatic
  def initialize(app, options)
    @app = app
    @static = Rack::Static.new(@app, options)
  end

  def call(env)
    rack_static_response = @static.call(env)
    if rack_static_response[0] == 404
      @app.call(env)
    else
      rack_static_response
    end
  end
end

use TryStatic, :urls => ["/css"]
use TryStatic, :urls => ["/css"], :root => "/Users/karl/Desktop/test_rack/mha"

run MyApp.new

This could be more performant.
