I am unable to edit the code.Please use this code in Page_Init event..If your are using master page in then put this in master.aspx.cs file.

protected void Page_Init(object sender, EventArgs e)
{

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Response.Cache.SetNoStore();

}

Yes, Abhay Kumar Raut's post fix the issue. But the catch is, if the "Back" button is clicked, previous page URL is shown rather than "Log out" page URL.

you can check session varibale valu in master page

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
if (Convert.ToString(Session["Username"]) != "")
{ }
else
{
Response.Redirect("admin_login.aspx");
}
}
}

Nice article...

One trick is here

1. Create one interstitial page say "LogOutInter.aspx"
2. write the logout code which is suggested in this article on logout button or link (not in interstitial page) and redirect to LogOutInter.aspx.
3. in LogOutInter.aspx load event check the urlreferrer if it is coming from the logoff button redirect to your home page or default page. else if it is coming from other pages redirect to same page which you got from urlreferrer.

So when you click to logoff you go to LogOutInter.aspx and from there some other page. When user clicks back button while is on some other page we will redirect to LogOutInter.aspx and from there again to some other page.
