IIS中User-mode caching引起的Cache-Control不为public问题的解决方法

web.config中对应的配置如下：

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"

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>
