Set session Timeout and Auto Redirect

[visweswaran2830]

Hi,

I am creating web application. In that I want to set session timeout (not idle timeout). If a user logged in that time the session time will start and it automatically should detect session timeout the page should redirect to another page. How can I acheive this.

Since this code is going to be on every page in your website I recommend that you create a "base page class" that all of your pages can inherit from. This way you can implement the code that checks Session once instead of having to copy/paste the code into every page.

That being said, I recommend that you put something into Session when the user logs in. That way you can retrieve it from Session and check if it is Null/Nothing to determine whether or not Session has ended.

So, when the user logs in set something in Session like:
(VB.NET)

Dim userName As String = "name"
Session("UserName") = userName

(C#)

string  userName = "name";
Session["UserName"] = userName;

Now, in every Page Load event check if anything in Session["UserName"] exists...if it doesn't then you know their Session has expired (or otherwise abandoned) and in this case you want to redirect them.
(VB.NET)

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
  If Session("UserName") Is Nothing Then
    Response.Redirect("otherPage.aspx",true)
  End If
End Sub
 

(C#)

protected void Page_Load(Object sender, EventArgs e)
{
  if(Session["UserName"] == null)
  {
    Response.Redirect("otherPage.aspx",true);
  }
}
