Session Using in Asp.Net C#

SESSION

The session state is used to maintain the session of each user throughout the application.

  Session allows information to be stored in one page and access in another page and support any type of object. 
The Session object stores information about, or change settings for a user session.

Variables stored in a Session object hold information about one single user, and are available to all pages in one application.

 Common information stored in session variables are name, id, and preferences.

 The server creates a new Session object for each new user, and destroys the Session object when the session expires.
