Cookie eval

cookie = { 499 => 1, 500 => 1, 498 => 1, 502 => 1, 504 => 1, 507 => 1, 497 => 1 }

# When loading the cookie back in another action, the cookie is a string instead of a hash.

eval(cookie)

# But I don't want to do eval on a cookie since I would leave my app vulnerable to attack since ruby code would be able to fire up from the client
