Web is Stateless, means a new instance of the web page class is re-created each time the page is posted to the server.

If user inserts some information, and move to the next page, that data will be lost and user would not able to retrieve the information. So what we need? we need to store information.

Now lets have a look at the advantages and disadvantages of using session in our web application.
