Asp – How to make a beta access page like the one on superuser.com

In the RTM version of ASP.NET MVC, the Cancel property is missing. This code works with ASP.NET MVC RTM:

using System;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Resources;

namespace ePegasus.Web.ActionFilters
{
    public class CustomAuthorize : AuthorizeAttribute
    {
        public override void OnAuthorization(AuthorizationContext filterContext)
        {
            base.OnAuthorization(filterContext);
            if (filterContext.Result is HttpUnauthorizedResult)
            {
                filterContext.Result = new RedirectToRouteResult(
                    new System.Web.Routing.RouteValueDictionary
                        {
                                { "langCode", filterContext.RouteData.Values[ "langCode" ] },
                                { "controller", "Account" },
                                { "action", "Login" },
                                { "ReturnUrl", filterContext.HttpContext.Request.RawUrl }
                        });
            }
        }
    }
}

Edit: You may want to disable the default forms authentication loginUrl in web.config - in case somebody forgets you have a custom attribute and uses the built in [Authorize] attribute by mistake.

Modify the value in web.config:

 <forms loginUrl="~/Account/ERROR" timeout="2880" />

Then make an action method 'ERROR' that logs an error and redirects the user to the most generic login page you have.

www.site.com can be handled by an root map route

routes.MapRoute(
    "Root",
    "",
    new { controller = "Home", action = "Index", id = "" }
);

Put the following in page load of Default.aspx

HttpContext.Current.RewritePath(Request.ApplicationPath, false);
IHttpHandler httpHandler = new MvcHttpHandler();
httpHandler.ProcessRequest(HttpContext.Current);

This rewrites the request to root and handled by the map route above.

BTW, you can actually find the code from the MVC template project.
