    You will need to make sure the pages behind the login (those that can only be accessed after login) are not cached in the browser:

    Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);

    If using forms authentication, you will also need to abandon the session and logout:

    Session.Abandon();
FormsAuthentication.SignOut();

    See this, this and this.
