Another efficient way on every page..

protected override void OnPreRender(EventArgs e)
   {
   base.OnPreRender(e);
   string strDisAbleBackButton;
   strDisAbleBackButton = "";
   ClientScript.RegisterClientScriptBlock(this.Page.GetType(), "clientScript", strDisAbleBackButton);
   }

Response.CacheControl = "no-cache";
Response.AddHeader("Pragma","no-cache");
Response.Expires = -1;
This will make the browser go to the server everytime the back button is clicked (for that particular page) and prevent any caching of the pages

I have tried this code it useful to you try id write this code in master page in page load event Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1)); Response.Cache.SetNoStore(); write this code in login page in head section window.history.forward(-1);

protected void Logout_Click(object sender, EventArgs e)
    {
        Session.Abandon();
        FormsAuthentication.SignOut();
        Response.Cookies["TestCookies1"].Expires = DateTime.Now.AddYears(-1);
        Response.Cookies["TestCookies2"].Expires = DateTime.Now.AddYears(-1);
        Response.Redirect("~/login.aspx");
    }

Try this on logOut, It wud help u and still thr is same issue then
try this after writing upper portion. (its customized method of doing the same :) )
write a method on the load of masterpage

function GoBack() {
            if (document.cookie == "")
                document.location = '<%=HttpContext.Current.Request.ApplicationPath%>' + "/login.aspx";
        }

Don't forget to mark it as answer, if it works....

Hi
To meet your requirement there is need to add two page login.aspx and logout.aspx. Write the code eg. Response.Redirect("logout.aspx") on logout button that redirect you to Logout.aspx page.On logout.aspx page write this code.
protected void Page_Load(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
sb.Append("");
Page.RegisterClientScriptBlock("disable", sb.ToString());
}
when ever you redirect on logout.aspx page the above code at once redirects to login page and at seems that you are always on login page.
