Auto redirect when session time out in Asp.net

Here is the scenario when user logged in to our website and keeps it on then after certain period of time when session gets expired then it should automatically redirect to login page.

 Here are the steps to simply just follow it and you are done;

 Step 1: Make sure you have session start and session end method in your Global.asax file

protected void Session_Start(object sender, EventArgs e)

        {

            // Check user session 

            if (Session["userSession"] != null)

            {

                //Redirect to Home Page if Session is not null 

                Response.Redirect("Index.aspx");

            }

            else

            {

                //Redirect to Login Page if Session is null & Expires  

                Response.Redirect("Login.aspx");

            }

        }

        protected void Session_End(Object sender, EventArgs e) {

            Session.Clear();

            Session.Abandon();

        }

Step 2: Make sure you have below code in your web.config file

<sessionState timeout="5"></sessionState> <!—Session time out in minutes-->

Step 3: Now, add below code in your page (in master or any page) in .aspx.cs on page load

Response.AppendHeader("Refresh", Convert.ToString((Session.Timeout) * 60) + "; URL=Login.aspx");

Here Session.Timeout is your web.config time out

Now, you are done. When user session time out then it automatically redirect to home page.
