Store data on the client

HTML5 provides two new ways to store data on the client:

    • Localstorage-Data storage with no time limit
    • Sessionstorage-Data storage for a session

Previously, these were all done by cookies. However, cookies are not suitable for storing large amounts of data because they are passed by each request to the server, which makes the cookie slow and inefficient.

In HTML5, the data is not passed by each server request, but only when the data is used on the request. It makes it possible to store large amounts of data without compromising site performance.

For different sites, the data is stored in different regions, and a Web site can only access its own data.

HTML5 uses JavaScript to store and access data.

Localstorage method

The data stored by the Localstorage method has no time limit. Data is still available after the second, second, or next year.

How to create and access localstorage:

Instance
<script type= "Text/javascript" >localstorage.lastname= "Smith";d ocument.write ( Localstorage.lastname); </script>
