如何利用 .woff 字体的浏览器缓存？

在 PageSpeed Insights 中，我不断看到利用浏览器缓存我正在使用的特定图标集/字体的消息：iconFont.woff（2 天）

我已将 .htaccess 设置为：

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType font/ttf "access 1 week"
ExpiresByType font/woff "access 1 week"
ExpiresByType image/jpg "access 1 month"
ExpiresByType image/jpeg "access 1 month"
ExpiresByType image/gif "access 1 month"
ExpiresByType image/png "access 1 month"
ExpiresByType text/css "access 1 week"
ExpiresByType application/pdf "access 1 month"
ExpiresByType application/javascript "access 1 month" 
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"
</IfModule>
## EXPIRES CACHING ##

尽管如此，我仍然在 PageSpeed Insights 中收到相同的消息。我如何正确缓存它？

这对我来说已经完成了这项工作，因为谷歌页面速度不再要求修复它。 AddType 是必不可少的。

# Fonts
# Add correct content-type for fonts
AddType application/vnd.ms-fontobject .eot 
AddType application/x-font-ttf .ttf
AddType application/x-font-opentype .otf
AddType application/x-font-woff .woff
AddType image/svg+xml .svg

# Compress compressible fonts
# only uncomment if you dont have compression turned on already. Otherwise it will cause all other filestypes not to get compressed
# AddOutputFilterByType DEFLATE application/x-font-ttf application/x-font-opentype image/svg+xml

# Add a far future Expires header for fonts
ExpiresByType application/vnd.ms-fontobject "access plus 1 year"
