为什么我的 web.config 文件出现错误
我将以下部分添加到我的 web.config 中：
<system.webServer>
<caching>
<profiles>
<add extension=".html" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".htm" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".gif" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".js" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".css" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".jpg" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
</profiles>
</caching>
</system.webServer>
这是 直接从这里
但我在我的web.config中收到错误，说：
无法识别的配置部分system.web/caching/profiles
另外，我在Visual Studio中看到了这一点： 
元素缓存具有无效的子元素“配置文件”，可能的预期列表：缓存、输出缓存，outputcacheSettings，sqlCacheDependency'
对此配置进行了一些更改，因为我在网络上看到了很多具有此精确配置的示例？
I have the following section added to my web.config:
<system.webServer>
<caching>
<profiles>
<add extension=".html" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".htm" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".gif" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".js" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".css" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
<add extension=".jpg" policy="CacheUntilChange" kernelCachePolicy="DontCache" location="Client" />
</profiles>
</caching>
</system.webServer>
which was taken directly from here
but I am getting an error in my web.config, saying:
Unrecognized configuration section system.web/caching/profiles
also, I see this in visual studio:
The element caching has invalid child element 'profiles', List of possible expected: cache, outputcache, outputcacheSettings, sqlCacheDependency'
did something about this configuration change as I see alot of examples on the web with this exact configuration?

在您的屏幕截图中，您的缓存位于
下的有效元素。 caching>forIn your screenshot you have the caching under
<system.web>and not<system.webServer>and since profiles is not a valid element under<caching>for<system.web>you will get that error.您在代码示例中显示的内容位于
What you show in code example is under
<system.webServer>, what you show in your screenshot is under<system.web>, it needs to be under webServer for it to get the profiles option, under system.web like you had it offers all those options that the error you received was talking about, behaves differently depending on where you call it from
