localStorage, Cookie or Session


Nowadays more websites focus on user experience, and creating customized contents for users. One solution is creating an identifier ID for each user, then rendering customized contents based on the ID. To store that identifier and customized content, we can use LocalStorage, Cookie or Session. Cookie can contain 4K data in the browser, it is included in every httpRequest’s header. Every time when browser sends a request to server, the server will receive Cookie data. The problem is it loads much slower with increase of Cookie size. The good part is Cookie has an expiration date. It stays in the browser until it expires or users clear Cookie. Session is something we can use on server side to store data, which means the data will be not visible to users. Session usually stores sensible data you do not want to share with different users, but it will expire after closing browser window. Session is perfect for tracking user activity during a certain period, for example: shopping cart order funnel. Another good part is Session has unlimited size. LocalStorage is a feature in HTML5, it stores data in browser and only can be accessed in JavaScript. It is useful when the website involves large interactions and data exchange with a spotty network connection. The data could be stored in LocalStorage first, then be sent to server when the connection is back. LocalStorage does not have an expiration date, and it only 5MB limit, much larger than Cookie. Depending on where you want to access those data, you can choose LocalStorage, Cookie or Session. LocalStorage needs JavaScript turned on to make sure work properly. Usually if you only want to store and access data in browser, LocalStorage is a good option. If you want to store an identifier ID, and use that ID to retrieve customized contents, then you can use Cookie to store that ID, then use that ID to retrieve customized data from database.

The SEO has a technical background, so they want to do something special, rather than copy others’ work. The site mainly appeals to white-collar workers. and are owned by Tencent, a large player in China. Tencent also developed QQ – a messaging platform similar to MSN or AIM. QQ is a powerhouse- boasting 647,000,000 users in China. Tencent has leveraged this user base to grow both and is a social network that works with the QQ platform.

Sina has grown from 100 Million as of January 2011, to over over 200 Million now (11/9).

Again, Tencent’s 647 Million registered users makes it easy for them to crowd out smaller websites.
