web.config中对应的配置如下：

复制代码 代码如下:
<configuration>
<system.webServer>
<caching>
<profiles>
<add extension=".css" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange" duration="00:00:30" />
<add extension=".js" policy="CacheUntilChange" kernelCachePolicy="CacheUntilChange" duration="00:00:30" />
</profiles>
</caching>
</system.webServer>
</configuration>

浏览器中看到的效果：

解决方法：

1、禁用User-mode caching，只用Kernel-mode caching。

2、在web.config中加上cacheControlCustom="public"

复制代码 代码如下:
<configuration>
<system.webServer>
<staticContent>
<clientCache cacheControlCustom="public" cacheControlMode="UseMaxAge" cacheControlMaxAge="300.00:00:00" />
</staticContent>
<caching>
<profiles>
<add extension=".css" policy="DontCache" kernelCachePolicy="CacheUntilChange" duration="30:00:30" />
<add extension=".js" policy="DontCache" kernelCachePolicy="CacheUntilChange" duration="30:00:30" />
</profiles>
</caching>
</system.webServer>
</configuration>
