There are the following benefits of using cookies for state management:
  • No server resources are required as they are stored in client.
  • They are light weight and simple to use.

There are the following limitations of using cookies:
  • Most browsers place a 4096-byte limit on the size of a cookie, although support for 8192-byte cookies is becoming more common in the new browser and client-device versions available today.
  • Some users disable their browser or client device's ability to receive cookies,
    thereby limiting the use of cookies.
  • Cookies can be tampered and thus creating a security hole.
  • Cookies can expire thus leading to inconsistency.
