Create filter to redirect page to login page on direct hit URL in MVC.

Steps:

1. Add a new folder Name it Filter.

2. Add a new class name it NoDirectAccessAttribute.  

3. Inherit ActionFilterAttribute

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using System.Web.Routing;

namespace DotNetByPriyanshu.Filter

{

    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]

    public class NoDirectAccessAttribute : ActionFilterAttribute

    {

        public override void OnActionExecuting(ActionExecutingContext filterContext)

        {

            if (filterContext.HttpContext.Request.UrlReferrer == null ||

                        filterContext.HttpContext.Request.Url.Host != filterContext.HttpContext.Request.UrlReferrer.Host)

            {

                filterContext.Result = new RedirectToRouteResult(new

                               RouteValueDictionary(new { controller = "Login", action = "Login", area = "" }));

            }
