    • Can you log yourself out by manipulating a cookie? Can you log yourself back in?
  • Understand what domains mean to cookies
    • Can cookies be shared between domains?
    • Between subdomains?
    • How does a tool like Google Analytics work?
  • How do cookies expire? What are "session" cookies?
  • What does a cookie's "secure" flag do? It it still relevant with HSTS?

Exercise: Star movies

  • In your MovieDB, implement a feature to star / unstar your favorite movies.
  • Implement this with cookies or sessions without writing anything to the database.
  • Try two separate ways of implementing this:
    • Make an AJAX call and have the server set the cookies
    • Set cookies directly on the client
  • Is this a good way to implement the star feature?
