Hello guys, i made a simple project that allows a user to go to another pages and in that page his name is displayed but after a minute the page will directly go back to the index page. How do i make a condition to determine that the alloted time is already met to redirect the page back to the index page? Hoping for your positive response. Thanks.

index page code

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
        Session("name") = TextBox1.Text
        Response.Redirect("profile.aspx")
    End Sub

profile page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
dim timeLogger as integer
        Label1.Text = Session("name")

        Session.Timeout = 1
        timeLogger = Session.Timeout
        Label2.Text = timeLogger

        'If timeLogger = timeLogger Then
        '    Response.Redirect("index.aspx")
        'End If
    End Sub
