Subject: Can you rewrite this ruby form post with rack?

require 'rack'
require 'json'

class MyApp
  def call(env)
    #puts JSON.pretty_generate(env)
    @req = Rack::Request.new(env)
    case @req.path
      when '/'
        body = <<-HTML
          <form action="/post_test" method="post">
            Username: <input type="text" name="username" /><br/>
            <input type="submit" name="submit" />
          </form>
          HTML
          return [200, {'Content-Type' => 'text/html'}, [body]]
      when "/post_test"
        if @req.post?
          return [200, {'Content-Type' => 'text/plain'},
          ["you sent this POST data:n",JSON.pretty_generate(@req.POST)]]
        end
    end
    [404, {}, ["not found oO"]]
  end
end

app = Rack::Builder.new{
  use Rack::ShowExceptions
  use Rack::Lint
  use Rack::ContentLength
  run MyApp.new
}.to_app

Rack::Handler::WEBrick.run(app, :Port => 4000)

# run ruby <this-file>
# and visit http://127.0.0.1:4000/ in your browser.
# Content-Encoding


What i'm trying to seperate the html form from inside ruby code.
Put the .html file in /var/www and put the .rb file seperate. Click the
form and it will execute the ruby code like:
<form action="file.rb" method="POST" >
...
</form>

Is it possible with apache webserver. Use fusion passenger if necessary.
Don't re-write with CGI or something like cgi, rather try with rack.

Thanks.
