    Response.End()

  When I click a button in the result form ,then   Response.End() will be called. But from that form (End) I can go back to  result form.

  Do you want to disable the goback button on the page? If so, you can try below code.

  The preventBack() method disable the goback button.

  <script type="text/javascript">
          function preventBack() { window.history.forward(); }
          setTimeout("preventBack()", 0);
          window.onunload = function () { null };
      </script>
  
  <form id="form1" runat="server">
          <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
      </form>
  
  protected void Button1_Click(object sender, EventArgs e)
          {
              Response.Write("This is the refreshed page");
          }

  The result:

  There are 4 solutions describe here

  https://lennilobel.wordpress.com/2009/07/26/defeat-the-evil-back-button-in-your-asp-net-applications/

  For Server Side:

  protected override void OnPreInit(EventArgs e)
  {
      base.OnPreInit(e);
   
      Response.Buffer = true;
      Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d);
      Response.Expires = -1500;
      Response.CacheControl = "no-cache";
      Response.Cache.SetCacheability(HttpCacheability.NoCache);
  }
