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

小蚂蚁

web.config中对应的配置如下：

<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"

<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>
