You've only passed one parameter. The first "foo=1" sets the foo parameter to 1. The second "foo=3" re-assigns foo to 3. If you want two parameters to be passed to your app, you need to define two separate parameters.

Hello everyone.

I'm using rack (1.4.1), but it seems cannot receive
checkbox selection value..

http://localhost/hello.cgi?foo=1&foo=3
Hello, Rack
{"foo"=>"3"}

Code below.

#!ruby
require "rack"
class HelloRack
def call(env)
req = Rack::Request.new(env)
return [200, {"Content-Type" => "text/plain"},
"Hello, Rack\n" + req.params.inspect ]
end
end
Rack::Handler::CGI.run HelloRack.new

Could anyone tell me idea?
