.htaccess - Google Page Speed 利用浏览器缓存未标记为已解决

Question

在页面速度测试中，我几乎没有要解决的警告，例如:

Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

然后它指向本地 .js 和 .css 文件

但是我的 htaccess 中有这个:

<FilesMatch "\.(js|css|ttf)$">
    Header set Cache-Control "max-age=604800, public"
</FilesMatch>
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">
    Header set Cache-Control "max-age=604800, public"
</FilesMatch>
<FilesMatch "\.(html|htm|php)$">
    Header set Cache-Control "max-age=60, private, proxy-revalidate"
</FilesMatch>
<FilesMatch "\.(css|js|gif|jpeg|png|ico)$">
ExpiresActive On
ExpiresDefault "access plus 1 year"
</FilesMatch>

知道我做错了什么吗？

好吧，这是在黑暗中拍摄，但我遇到了 Apache 不尊重我的情况 .htaccess标题，我不得不用 always“强制”它们像这样的关键字:

<FilesMatch "\.(js|css|ttf)$">
    Header always set Cache-Control "max-age=604800, public"
</FilesMatch>
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">
    Header always set Cache-Control "max-age=604800, public"
</FilesMatch>
<FilesMatch "\.(html|htm|php)$">
    Header always set Cache-Control "max-age=60, private, proxy-revalidate"
</FilesMatch>
<FilesMatch "\.(css|js|gif|jpeg|png|ico)$">
    ExpiresActive On
    ExpiresDefault "access plus 1 year"
</FilesMatch>

When your action is a function of an existing header, you may need to specify a condition of always, depending on which internal table the original header was set in. The table that corresponds to always is used for locally generated error responses as well as successful responses. Note also that repeating this directive with both conditions makes sense in some scenarios because always is not a superset of onsuccess with respect to existing headers:

• You're adding a header to a locally generated non-success (non-2xx) response, such as a redirect, in which case only the table corresponding to always is used in the ultimate response.
• You're modifying or removing a header generated by a CGI script, in which case the CGI scripts are in the table corresponding to always and not in the default table.
• You're modifying or removing a header generated by some piece of the server but that header is not being found by the default onsuccess condition.
