對于一個剛剛創(chuàng)建網(wǎng)站，以ASP.NET MVC5為例。

我們并沒有在網(wǎng)頁的配置文件(web.config)中配置一些處理程序或模塊，如處理Session的SessionStateModule模塊，映射Url的UrlRoutingModule模塊等。

但是我們依然可以在控制器中正常的訪問Session。我們請求的url依然能正確的映射到控制器和Action。

這是因為在IIS的配置文件中ApplicationHost.config的modules 元素中注冊了很多模塊 ，這些模塊供IIS承載的所有應(yīng)用程序使用。

在 ApplicationHost.config 文件中注冊的模塊具有全局范圍，因為它們?yōu)樗杏?IIS 承載的 Web 應(yīng)用程序而注冊。

同樣，在 ApplicationHost.config 文件的 globalModules 元素中定義的本機(jī)代碼模塊也具有全局范圍。如果 Web 應(yīng)用程序不需要全局模塊，則可以將其禁用。

當(dāng)然這也只是這個配置文件的功能的一小部分，有時我們在IIS管理器中添加的映射關(guān)系等也都會存儲在這個配置文件中。

但是沒有十足的把握，不要修改這個配置文件或在修改前進(jìn)行備份。因為這個文件供整個IIS承載的所有應(yīng)用程序使用。一些不起眼的配置節(jié)點的丟失，對某些程序可能就是致命的。

下面我們列出這個配置文件的部分內(nèi)容，大家也可以再自己的電腦C盤中搜索這個文件，詳細(xì)的查看其中的內(nèi)容。

上面的配置節(jié)點中列出的都是本機(jī)代碼模塊(native-code)。大家如果要添加自己的托管代碼模塊(managed-code)，就添加早modules中。

然后通過環(huán)境變量去讀取這些文件。他們是整個iis的基石。

上面可以看出，我們在iis管理器中看到的模塊等配置信息就是來自這里，包括下面的處理程序映射，大家在iis里點擊處理程序映射，其中顯示的處理程序正式本配置文件

上面的處理程序是iis默認(rèn)配置的，可以看出，iis為了能在多種環(huán)境下運行(包括不同的.net framework版本，不同的cpu版本)，以處理 *.aspx 為例，來分析一下這種設(shè)置。

在集成模式下，只對運行時版本進(jìn)行了區(qū)分，因為托管代碼會被編譯為中間語言，中間語言在使用了時會根據(jù)運行機(jī)器的cpu型號編譯為本地代碼(nativa-code)。所以不需要有bitness64這樣的配置。

在經(jīng)典模式下，asp.net只是作為iis的一個ISAPI的擴(kuò)展，而且不同的Framework版本和運行時版本已經(jīng)編譯好具體的aspnet_isapi.dll,所以使用時只需根據(jù)具體的運行機(jī)器的情況選擇對應(yīng)的dll即可。

iis配置存儲區(qū)中的文件供整個iis支持的應(yīng)用程序使用，對不同的本地環(huán)境做了適配，沒有十足的把握和了解，盡量不要修改這個文件。
