Question

What is the best way to show a message to user after session is expired?
By then, the user should be logged out and redirected to start page.
I can use javascript to redirect user to start page. I just want to show a message on start page.

Answer 1

In your JavaScript redirect add a querystring parameter to your redirect URL.

<script>
...
// If session is about to timeout...
location.href = '/home.aspx?action=expired';
...
</script>

Then in your start page, you can have code to check the querystring and display a message if that’s the case.

<%
'home.aspx
If Request.QueryString("action") = "expired" Then 
  Response.Write("<p>You have been logged out due to inactivity.</p>")
End If
%>
