对于一个刚刚创建网站，以asp.net mvc5为例。

我们并没有在网页的配置文件(web.config)中配置一些处理程序或模块，如处理session的sessionstatemodule模块，映射url的urlroutingmodule模块等。

但是我们依然可以在控制器中正常的访问session。我们请求的url依然能正确的映射到控制器和action。

这是因为在iis的配置文件中applicationhost.config的modules 元素中注册了很多模块，这些模块供iis承载的所有应用程序使用。

在 applicationhost.config 文件中注册的模块具有全局范围，因为它们为所有由 iis 承载的 web 应用程序而注册。

同样，在 applicationhost.config 文件的 globalmodules 元素中定义的本机代码模块也具有全局范围。如果 web 应用程序不需要全局模块，则可以将其禁用。

当然这也只是这个配置文件的功能的一小部分，有时我们在iis管理器中添加的映射关系等也都会存储在这个配置文件中。

但是没有十足的把握，不要修改这个配置文件或在修改前进行备份。因为这个文件供整个iis承载的所有应用程序使用。一些不起眼的配置节点的丢失，对某些程序可能就是致命的。

下面我们列出这个配置文件的部分内容，大家也可以再自己的电脑c盘中搜索这个文件，详细的查看其中的内容。

上面的配置节点中列出的都是本机代码模块(native-code)。大家如果要添加自己的托管代码模块(managed-code)，就添加早modules中。

然后通过环境变量去读取这些文件。他们是整个iis的基石。

上面可以看出，我们在iis管理器中看到的模块等配置信息就是来自这里，包括下面的处理程序映射，大家在iis里点击处理程序映射，其中显示的处理程序正式本配置文件

上面的处理程序是iis默认配置的，可以看出，iis为了能在多种环境下运行(包括不同的.net framework版本，不同的cpu版本)，以处理 *.aspx 为例，来分析一下这种设置。

ApplicationHost.config(IIS存储配置区文件)介绍

在集成模式下，只对运行时版本进行了区分，因为托管代码会被编译为中间语言，中间语言在使用了时会根据运行机器的cpu型号编译为本地代码(nativa-code)。所以不需要有bitness64这样的配置。

在经典模式下，asp.net只是作为iis的一个isapi的扩展，而且不同的framework版本和运行时版本已经编译好具体的aspnet_isapi.dll,所以使用时只需根据具体的运行机器的情况选择对应的dll即可。

iis配置存储区中的文件供整个iis支持的应用程序使用，对不同的本地环境做了适配，没有十足的把握和了解，尽量不要修改这个文件。
