Added same secure origin access control for cookies
  • Cookies vs Local Storage vs Session Storage.
  • Cookies
  • - Has different expiration dates (both the server or client can setup expiration date).
  • - Cookies themselves can specify which pages from which domains can access them.
  • - Client-side Javascript can be denied access to a cookie value by the cookie's `HttpOnly` attribute, even if the domain/path-based access policy would otherwise have allowed it.
  • - Data are transferred on each HTTP request.
  • - The max size for Cookies are 4KB.
  • More about [Cookies](https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies).
  • Use [`document.cookie`](https://developer.mozilla.org/en-US/docs/web/api/document/cookie) to create Cookies in JavaScript.
  • Local Storage
  • - Has no expiration date.
  • - Part of the browser-side "Web Storage". A web server is not involved in the function of the "Web Storage" mechanism.
  • - Access to data stored in "Web Storage" is strictly on a "same origin" basis. Only pages loaded from URLs that share the same origin (scheme, host and port) have access to the same data.
  • - Data are not transferred on each HTTP request.
  • - The max size for Local Storage is 5MB.
  • Use [`window.localStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage) to access the Storage.
  • Session Storage
  • - Data is gone when you close the browser tab.

  • - The max size for Session Storage is 5 to 10 MB.
  • Use [`window.sessionStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage) to access the session Storage.
  • This were some facts about Cookies & Local Storage & Session Storage. You can now choose which will fit your cause but likely it will be Local Storage but it is also your opinion.

Cookies vs Local Storage vs Session Storage.

Cookies

- Has different expiration dates (both the server or client can setup expiration date).
- The client can not access the Cookies if the `HttpOnly` flag is true.
- Has SSL support.
- Data are transferred on each HTTP request.
- The max size for Cookies are 4KB.

More about [Cookies](https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies). 

Use [`document.cookie`](https://developer.mozilla.org/en-US/docs/web/api/document/cookie) to create Cookies in JavaScript.

Local Storage

- Has no expiration date.
- Client only.
- Has no SSL support.
- Data are not transferred on each HTTP request.
- The max size for Local Storage is 5MB.

Use [`window.localStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage) to access the Storage.

Session Storage

- Data is gone when you close the browser tab.
- Client only.
- Has no SSL support
- Data are not transferred on each HTTP request
- The max size for Session Storage is 5 to 10 MB.

Use [`window.sessionStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage) to access the session Storage.

This were some facts about Cookies & Local Storage & Session Storage. You can now choose which will fit your cause but likely it will be Local Storage but it is also your opinion.
