How to disable browser back button in asp.net?

Hi,

When You logged out, Execute these Codes

Session.Abandon();
Session.Clear();

And you mentioned,that you are using Master Page for All Pages. So, you can include these Codes in Page_Load() of Master Page,

        if (Session["UserName"] == Null)
    {
            Session["ErrMsg"] = "Session Expired or Access Denied please login";
            Response.Redirect("../Login.aspx");
        }

Here is the solution

protected void Page_Init(object Sender, EventArgs e)
{
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
      Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
      Response.Cache.SetNoStore();
}

@Suthish,

After google i thought someone here could help me..
I know the disadvantages of javascript so did not go with it.

 Using iFrame is a big concern when it came for security. Hackers loves iFrame.

 The couple of ways you can handle the back button..

 1. Use above javascript code in Page Init of each web pages.
 Create an overirde method of OnInit and using Registerstartupscript adds Javascript to the web form. The disadvantage, if the Java Script is not working on client system then this method is of no use.

 2. The best and recommended method is using Response.Cache.
