def []=(name, options)
  if options.is_a?(Hash)
    options = options.inject({}) { |options, pair| options[pair.first.to_s] = pair.last; options }
    options["name"] = name.to_s
  else
    options = { "name" => name.to_s, "value" => options }
  end

  set_cookie(options)
end

#delete(name, options = {}) ⇒ Object

Removes the cookie on the client machine by setting the value to an empty string and setting its expiration date into the past. Like []=, you can pass in an options hash to delete cookies with extra data such as a :path.
