  Please refer - http://forums.asp.net/t/1865113.aspx/1?Logout+Issue+

  That's because the browser takes the page from cache. So even if you logout, the browser back/forward buttons can get the page from cache.

  Add the below code to your pages so those will not get cached on the browser.

  protected void Page_Load(object sender, EventArgs e)
  {
       if (!IsPostBack)
       {
          Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
          Response.Cache.SetCacheability(HttpCacheability.NoCache);
          Response.Cache.SetNoStore();
       }
  }

  That must be done in ever page so there are 2 Solutions, 1st for code behind, 2nd for HTML source
  but if the thing is not done, you can use both at once, on every page
  
  

  Response.Cache.SetExpires(DaeTime.UtcNow.AddMinutes(-1));
  Response.Cache.SetCacheability(HttpCacheability.NoCache);
  Response.Cache.SetNoStore();

  Second is through HTML source using meta tages

  <meta content="max-age=0" http-equiv="cache-control"> <meta content="no-store" http-equiv="cache-control"> <meta content="-1" http-equiv="expires"> <meta content="Tue, 01 Jan 1980 1:00:00 GMT" http-equiv="expires"> <meta content="no-cache" http-equiv="pragma">

  On Logout Page Load 

  protected void Page_Load(object sender, EventArgs e)
          {
              //RegisterHyperLink.NavigateUrl = "Register.aspx?ReturnUrl=" + HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"]);
              Response.ClearHeaders();
              Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
              Response.Cache.SetCacheability(HttpCacheability.NoCache);
              Response.Cache.SetNoStore();
              Response.AddHeader("Cache-Control", "no-cache, no-store, max-age=0, must-revalidate");
              Response.AddHeader("Pragma", "no-cache");
              Session.Clear();
              Session.Abandon();
          }

  Hiii

  Are you using form authentication?

  If yes then you also try with

  FormsAuthentication.SignOut()
  

  Session("User") = Nothing ' Your session varibale do it nothing.if it C# then null
  Session.Clear()
  Session.RemoveAll()
