利用浏览器缓存，在apache或.htaccess上如何？

php browser-cache .htaccess

2022-08-30 09:54:56

在这里做什么？我有一个巨大的文件列表，谷歌速度页面说“利用浏览器缓存”。但我不知道该怎么做？我是弄乱或更改Apache配置文件（如下图），还是在我的.htaccess页面中放入了一些东西？

 <IfModule mod_proxy.c>
        ProxyRequests Off
        CacheRoot "/var/run/proxy"
        CacheSize 1024
        CacheGcInterval 24
    #CacheMaxExpire 24
    #CacheLastModifiedFactor 0.1
    #CacheDefaultExpire 1
    #NoCache a_domain.com another_domain.edu joes.garage_sale.com
        <Directory "disabled_proxy">
            Allow from example.com
            Deny from all
            Order Deny,Allow
        </Directory>
    </IfModule>
    ##
    #### mod_expires is configured so that all static files but images
    #### expire after 60 seconds. Any response that has a life span of more
    #### than 5 seconds (see webperfcache.conf) will be cached by webperfcache.
    #### Make sure your CGIs return a "Cache-Control: no-cache" header if you
    #### elect to make your dynamically generated HTML pages not cache-able.
    #### If all your HTML pages are static you may also increase ExpiresDefault.

我借此机会提供了完整的代码来传递Google PageSpeed Insight：.htaccess

利用浏览器缓存

# Enable Compression

</IfModule>

还有一些适用于各种Web服务器的配置，请参阅此处。
希望这将有助于获得100/100的分数。

几天前，我也在做同样的事情。已将其添加到我的 .htaccess 文件中：

ExpiresActive On
ExpiresByType image/gif A2592000
ExpiresByType image/jpeg A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/png A2592000
ExpiresByType image/x-icon A2592000
ExpiresByType text/css A86400
ExpiresByType text/javascript A86400
ExpiresByType application/x-shockwave-flash A2592000
#
<FilesMatch "\.(gif¦jpe?g¦png¦ico¦css¦js¦swf)$">
Header set Cache-Control "public"
</FilesMatch>

现在，当我运行Google速度页面时，杠杆眉毛器缓存不再是高优先级。

希望这有帮助。
