Reading and Writing Values to the Session Object

You can store user-specific information, such as a user's name, in the Session collection.

Because the Session collection is user specific, it should not be written to by multiple

threads concurrently.Therefore, you do not need to use locks around your writes, as you

must with the Application collection . Otherwise, the syntax is similar:

Session("UserName")=UserNameTextBox.Text

UserNameLabel.Text = Session("UserName")

Comments

By default, the Session collection holds data for 20 minutes after the last request to an

application by a particular user.You can adjust this time period in the application's con-

figuration . Because data stored in sessions can grow linearly with the

number of users, and because it persists for quite some time after each user leaves, it can

quickly impede scalability if it is used to store large amounts of data. It should therefore

be used sparingly.
