使用 ASP.NET MVC 的 IIS 应用程序请求路由 (ARR)

Question

我使用一个简单的 ASP.NET MVC Web（创建新站点时使用的模板），并且该 Web 在我的实时环境中按预期工作。

我现在尝试使用 IIS 应用程序请求路由版本 2。我有一个规则，将所有请求发送到与规则匹配的不同服务器。

设置有点像这样： http://blogs.iis.net/wonyoo/archive/2008/07/09/application-request-routing-arr-as-a-reverse-proxy.aspx

< img src="https://blogs.iis.net/blogs/wonyoo/reverseproxy.jpg" alt="alt text">

我的规则有点不同，它是 /shop(.*)。 只有包含商店的请求才会发送到不同的服务器。我必须使用重写，而不是重定向（与图片中相同）

只要原始请求转到非 ASP.NET MVC Web，这就可以工作。我尝试在网络文件夹中使用纯 htm 文件并且它有效。如果将编译好的 ASP.NET 应用程序放入 web 文件夹中，它就可以工作。但是，一旦我将 ASP.NET MVC Web 放入该文件夹，就会请求该应用程序提供服务。

我的理解是，ARR 应该在 Web 应用程序有机会处理请求之前启动。 有人成功使用 ARR 作为 ASP.NET MVC Web 的反向代理吗？

编辑

这是输入重写规则后生成的 Web 配置。通过此规则，我得到 404，表明该规则未使用。

Answer 1

在 Global.asax.cs 文件中添加以下路由条目：

routes.IgnoreRoute("Shop/{*pathInfo}");

这解决了我的问题。

看来 MVC 路由系统在 ARR 之前启动，这在集成模式下运行时是有意义的。

Answer 2

我们的设置几乎与您描述的完全相同。我们发现 MVC 和 ARR 在同一个站点中不会很好地规划。我怀疑是因为 MVC 路由和 ARR 路由做了类似的事情并且相互干扰。为了解决这个问题，我们必须将 ARR 规则放在一个单独的网站中。域和所有内容都指向 ARR 站点，然后该站点会将请求发送到需要发送的位置。

我们有处理特定情况的特定规则，以及最后将其余请求发送到 MVC 站点的包罗万象的规则。

Answer 3

基本上，问题是 ASP.NET MVC 应用程序不太期望 /Shop 成为 url 的一部分，并且正在采取相应的行动。解决此问题的最佳方法是将 MVC 应用程序部署到 /Shop 代理站点中的应用程序中。这样就不需要翻译到子 URI 以及由此带来的所有乐趣。

Answer 4

我刚刚发现，如果您将重写规则放在服务器级别，它们将被保存到 system.webServer\rewrite\globalRuels 内的 %systemroot%\system32\inetsrv\config\applicationHost.config 中，并且将工作。

但我仍然想知道为什么它不适用于 Web.config 中的规则。

Answer 5

听起来 ASP.Net MVC 和 ARR 的 HttpModule 注册顺序错误。

您能向我们展示您的 web.config 吗？
