  1. Probably one of the best articles I have read! (in a long while)

    Good job and great explanation of how cookies defer from Local- & session storage. Learned a lot of new concepts here including security vulnerabilities regarding cookies and how to properly use cookie attributes.

  2. Thank you for this comprehensive article. Would you know if browsers, iOS Safari in particular, would start treating a cookie set in js as an http cookie if the server updates that cookie in a future request? For instance by changing the expiry date.
