Hi,

The other thing that you can try is clear the with the following code assuming that yours is an mvc application

C#

public class NoCache : ActionFilterAttribute
  {
      public override void OnResultExecuting(ResultExecutingContext filterContext)
      {
          filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
          filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
          filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
          filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
          filterContext.HttpContext.Response.Cache.SetNoStore();
      }
  }

Windows Forward[^]
Manipulate Browser History[^]
Disabling browser back button, you should not or say you cannot. Check the links I have provided. These just maipulate with the browsers history letting you feel the Back button is disabled but not exactly.
Window.History.Forward() is a simple one. Which prevents the user going back to previous page. The second link helps you find more methods to manipulate on this.
Hope this helps.
Post back your queries if any.
Thanks.
