我无法将图像文件缓存.我已尝试过在本网站和其他网站上找到的所有内容,但仍然无法让它们缓存.

我尝试过的Web配置设置

    <staticContent>
    <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" />
    </staticContent>
    <httpProtocol allowKeepAlive="true" />


    <caching enabled="true" enableKernelCache="true">
    <profiles>
    <add extension=".png" policy="CacheUntilChange" />
    <add extension=".jpg" policy="CacheForTimePeriod" duration="12:00:00" />
    </profiles>
    </caching>  

以下是其中一个图像的响应标题
