::::|| VU ||:::: HTML5: Web Data Storage Methods - [eTechy101.com]

The post title is 'HTML5: Web Data Storage Methods'. Below is a preview of the

of HTML, our main focus in this article would be discussing the data storage
methods employed in HTML5. HTML5 maintains two basic methods for data storage:
Permanent storage of data known as 'localStorage' and temporary storage of
data for specific sessions known as 'sessionStorage'. Previous versions of
HTML did store data but that was done through cookies and two disadvantages
govern data storage by cookies: First, cookies are unable to store large amount
of data and second, data is stored with cookies with each request to the server.
On the contrary, in HTML5, data is stored only when asked for, not with every
subsequent request after establishing the connection with server.

The data will be available the next day, week, or year. For example, consider
