What is Session In Asp.Net

Asp.Net Session are used to store and retrieve data when the user navigate from one page to other. That means, when a user needs some information from current page that can be used in another page, then that information can be assigned to Session and the information can be retrieved from Session when the user navigate to the other page.

Session Object are initialized when the user stores some information in Session Variable or when the user initialize the Session_Start method on Global.asax page. If the page is inactive for a particular period of time (by default 20 minutes), then the Session will not be active. We can increase or decrease the Session timeout so that the Session Object can be active as per out requirement.
