We know HTTP is stateless Protocol, it means a new instance of webpage class created each time the page post back. It can’t hold data on page. So to maintain data between different pages, we use Session. Session provides the facility to store information on server.

In this article I will explain how to remove sessions in ASP.NET.

//Storing UserName in Session

Session["SessionName "] = txtUser.Text;

In VB.Net

'Storing UserName in Session

Session("SessionName ")= txtUser.Text
