Session Objects

Sessions in ASP.NET are simply hash tables in the memory with a timeout specified.

Session

(“username”) = “Aayush Puri”
Session(“color”) = “Blue”

Sessions in ASP.NET are identified using 32-bit long integers known as Session IDs. The ASP engine generates these session ID’s so that uniqueness is guaranteed.

Session Type	What it does	Example
Session.Abandon	Abandons (cancels) the current session.
Session.Remove	Delete an item from the session-state collection.	Session(“username”) = “Aayush Puri” (Initialize a session variable) Session.Remove(“username”) (Deletes the session variable “username”)
Session.RemoveAll	Deletes all session state items
Session.Timeout	Set the timeout (in minutes) for a session	Session.Timeout=30 (If a user does NOT request a page of the ASP.NET application within 30 minutes then the session expires.)
Session.SessionID	Get the session ID (read only property of a session) for the current session.
Session.IsNewSession	This is to check if the visitor’s session was created with the current request i.e. has the visitor just entered the site. The IsNewSession property is true within the first page of the ASP.NET application.
