Question

当我们在生产服务器“/帐户/登录”上请求此网址时，我们收到404页面未找到错误，但“/ account / Login”工作正常。只有控制器第一个字母的情况不同。

此外，我们的开发服务器上没有此问题。

问题刚出现在最后几天，但我们没有看到路线配置发生任何变化。所以我不知道是什么原因导致了这个问题。

如果您看到可以解释的内容，那么这是RouteConfig.cs代码：

using System;
using System.Globalization;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace MobileWebsite.App_Start
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            if (routes == null) throw new ArgumentNullException("routes");

            const string defautlRouteUrl = "{controller}/{action}/{id}";
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            RouteValueDictionary defaultRouteValueDictionary = new RouteValueDictionary(
                    new { controller = "Home", action = "Index", id = UrlParameter.Optional });

            Route defaultRoute = new Route(defautlRouteUrl, defaultRouteValueDictionary, new MvcRouteHandler());
            routes.Add("DefaultGlobalisedClientSiteLang", new GlobalisedRouteClientSiteLang(defaultRoute.Url, defaultRoute.Defaults));
            routes.Add("DefaultGlobalisedClientSite", new GlobalisedRouteClientSite(defaultRoute.Url, defaultRoute.Defaults));
            routes.Add("DefaultGlobalised", new GlobalisedRoute(defaultRoute.Url, defaultRoute.Defaults));
            routes.Add("Default", new Route(defautlRouteUrl, defaultRouteValueDictionary, new MvcRouteHandler()));          
        }
    }

    public class GlobalisedRoute : Route
    {
        public const string CultureKey = "culture";
        static string CreateCultureRoute(string unGlobalisedUrl)
        {
            return string.Format(CultureInfo.InvariantCulture, "{{" + CultureKey + "}}/{0}", unGlobalisedUrl);
        }
        public GlobalisedRoute(string unGlobalisedUrl, RouteValueDictionary defaults) : 
            base(CreateCultureRoute(unGlobalisedUrl),
               defaults,
               new RouteValueDictionary(new { culture = new CultureRouteConstraint() }),

        }
        public GlobalisedRouteClientSiteLang(string unGlobalisedUrl, RouteValueDictionary defaults) :
            base(CreateClientSiteRoute(unGlobalisedUrl),
               defaults,
               new RouteValueDictionary(new { culture = new CultureRouteConstraint(), clientSiteId = new ClientSiteIdRouteConstraint() }),

               new GlobalisationRouteHandler())

        }
    }

    public class GlobalisationRouteHandler : MvcRouteHandler

事实证明这是ViewEngine缓存机制中的一个错误，请参阅此处的说明： http://blogs.msdn.com/b/rickandy/archive/2012/09/17/asp-net-mvc-4-mobile-caching-bug-fixed.aspx
