下面的配置文件示例演示如何以声明方式为HostingEnvironment 元素 (ASP.NET 设置架构)节指定值。The following configuration file example shows how to specify values declaratively for the hostingEnvironment Element (ASP.NET Settings Schema) section.

<system.web>  
  <hostingEnvironment  
    idleTimeout="20"  
    shutdownTimeout="30"  
  />  
</system.web>
