如何configurationARR – 应用程序请求路由 – 作为Web服务器和网关或代理运行?

我有这个IIS7.5 ARR安装和configuration为反向代理到运行IIS7的另一台服务器。

在这个IIS7.5我有ASP.NET 4应用程序和简单的网站安装。

由于在此IIS7.5上configuration场作为反向代理运行,本地应用程序不会运行此错误消息:

502 - Web server received an invalid response while acting as a gateway or proxy server. There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server. 

是否有可能在这个IIS7.5上同时运行本地应用程序和路由(反向代理),还是应该放弃并移动应用程序到另一个服务器?
