🍪 Setting Basic Cookies with Expiry​

Cookies allow you to store data client‑side and can persist after the browser is closed. In Rails, use the cookies helper in your controllers or views. You can specify options like expires to control how long the cookie lives.

class WelcomeController < ApplicationController
  def index
    # Set a cookie that expires in 7 days
    cookies[:visited_at] = { value: Time.current.to_s, expires: 7.days.from_now }
    render plain: "Welcome back! You last visited at #{cookies[:visited_at]}"
  end
end
