我认为这与全球有关。Asax，因为当我从主机我的网站运行当前删除它我的世界。asax代码

namespace officeWeb
{
    public class Global : System.Web.HttpApplication
    {
        protected void Application_Start(object sender, EventArgs e)
        {
            RegisterRoutes(RouteTable.Routes);
        }
        protected void Session_Start(object sender, EventArgs e)
        {
        }
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
            String fullOrigionalpath = Request.Url.ToString();
            String[] sElements = fullOrigionalpath.Split('/');
            String[] sFilePath = sElements[sElements.Length - 1].Split('.');
            if (!fullOrigionalpath.Contains("__browserLink"))
            {
                            //Rewrite
            if (!fullOrigionalpath.Contains(".aspx") && sFilePath.Length == 1)
            {
                Context.RewritePath(sFilePath[0] + ".aspx");
            }

        }

        public class WebServiceRouteHandler : IRouteHandler
        {

            {
                var assembly = typeof(System.Web.Script.Services.ScriptMethodAttribute).Assembly;
                var type = assembly.GetType("System.Web.Script.Services.ScriptHandlerFactory");
                ScriptHandlerFactory = (IHttpHandlerFactory)Activator.CreateInstance(type, true);
            }
            private string virtualPath;
            public WebServiceRouteHandler(string virtualPath)
            {
                this.virtualPath = virtualPath;
            }
            public IHttpHandler GetHttpHandler(RequestContext requestContext)
            {
                string pathInfo = requestContext.RouteData.Values["pathInfo"] as 
                if (!string.IsNullOrWhiteSpace(pathInfo))
                    pathInfo = string.Format("/{0}", pathInfo);
                requestContext.HttpContext.RewritePath(this.virtualPath, pathInfo, requestContext.HttpContext.Request.QueryString.ToString());
                var handler = ScriptHandlerFactory.GetHandler(HttpContext.Current, requestContext.HttpContext.Request.HttpMethod, this.virtualPath, requestContext.HttpContext.Server.MapPath(this.virtualPath));
                return handler;
            }
        }
    }
}

我该怎么办?
