apache - 为什么没有缓存图像？

Question

使用 CMS Bitrix。包含以下内容的站点根 .htaccess 文件：

<ifModule mod_headers.c>
<FilesMatch "\.(flv|swf|ico|gif|jpg|jpeg|png|css|js|text|bmp|psd)$">         
 Header set Cache-Control "max-age=172000"
 Header append Cache-Control "public, no-transform"
</FilesMatch>
</IfModule>

<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 5 seconds"
ExpiresByType image/x-icon "access plus 172000 seconds"
ExpiresByType image/jpeg "access plus 172000 seconds"
ExpiresByType image/png "access plus 172000 seconds"
ExpiresByType image/gif "access plus 172000 seconds"
ExpiresByType application/x-shockwave-flash "access plus 172000 seconds"
ExpiresByType text/css "access plus 172000 seconds"
ExpiresByType text/javascript "access plus 172000 seconds"
ExpiresByType application/javascript "access plus 172000 seconds"
ExpiresByType application/x-javascript "access plus 172000 seconds"
</ifModule>

如您所见，对于缓存标头的使用，过期。所以，来看看https://developers.google.com/speed/pagespeed/insights/ - 说“使用浏览器的缓存”，并指的是 .jpg 和 .png 文件未设置术语缓存的事实！但是上面的代码显示了set！有什么问题？
