HTML5 storage instead of cookies

NOT ON THE CURRENT EDITION
This blip is not on the current edition of the radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the radarUnderstand more

HTML5 storage, also known as local storage or web storage, is a mechanism for storing client side data in modern browsers, including iOS and Android mobile browsers. We recommend using HTML5 storage instead of cookies in almost all cases. HTML5 Storage can accommodate up to 5MB of data while cookies are limited to 4KB. Cookie data is transmitted in every request, which slows down your application and potentially exposes data over insecure HTTP connections. In contrast, HTML5 storage data remains securely in the browser. Cookies should be reserved for storing small simple pieces of data like a session ID.
