Session variables are used to store values that are required across multiple web pages .

A website can not remember anything about the users those who have already visited the site since the HTTP request does not have state . But at time , it is necessary to remember some details(eg should understand if a user is logged in or not ) . In such case we can use session that enable the website to store the information for later use .
