priya ji...
have U written this...?
on

C#

logout_Click
{
formsAuthentication.signout();
session.Abandon();
Response.Redirect("Login.aspx");
}

Now session is abandon So session variable wiil not have a value...
so u can redirect in Page_Load of Home.aspx

C#

Page_Load
{
if(!isPostback)
  {
   if(Session("ESrNo")<=0)
     {
      Response.Redirect("Login.aspx");
     }
     
  }
}

Hope It Will Work...
