帮我看看httpmodule实现无扩展名的URL重写

urls.config文件：
<?xml version="1.0" encoding="utf-8" ?>
<urls>
   <rewrite name="indexlogo"
         path="/logo_{0}/index.html"
         pattern = "/logo_(\d+)?/index.html"
         page="/indexlogo.aspx"
         querystring="brandpid=$1" />
</urls>
httpmodule类：
private void ReUrl_BeginRequest(object sender, EventArgs e)
        {            HttpContext context = ((HttpApplication)sender).Context;
            //string forumPath = "/0377autocarweb/";//xfly.web
            string forumPath = "/";//xfly.web
            string requestPath = context.Request.Path.ToLower();            if (requestPath.StartsWith(forumPath) && requestPath.IndexOf("/selectcar/") < 0 && requestPath.IndexOf("/images/") < 0 && requestPath.IndexOf("/tools/") < 0 && requestPath.IndexOf("test.aspx") < 0)
            {
                if (requestPath.EndsWith("/") && (requestPath.IndexOf(".html") < 0))
                {
                    requestPath = requestPath + "index.html";
                }
                foreach (SiteUrls.URLRewrite url in SiteUrls.GetSiteUrls().Urls)
                {                    if (Regex.IsMatch(requestPath, url.Pattern, Utility.GetRegexCompiledOptions() | RegexOptions.IgnoreCase))
                    {                        string newUrl = Regex.Replace(requestPath.Substring(forumPath.Length - 1), url.Pattern, url.QueryString, Utility.GetRegexCompiledOptions() | RegexOptions.IgnoreCase);
                        context.RewritePath(forumPath+url.Page, string.Empty, newUrl);
                        return;
                    }                }
            }        }
我在本机测试成功http://localhost:52857/0377AutoCarWeb/logo_1/     ->成功
放到服务器上测试http://127.0.0.1/logo_1/    ->不成功。提示“无法找到该页” HTTP 错误 404 - 文件或目录未找到。
